Their rules, (I believe unintentionally) give iron-fisted fiefdom rulers a toolbox of justifications to control and alienate under the guise of protecting the quality of the site data. I honestly don’t even think most of the control freak mods could objectively judge the propriety of their actions because it was all encouraged by the rules. (And I do not think this was universal among the mods, but it was certainly endemic to the site culture.) Well, the outcome was predictable.

Before I worked as a web developer, I was a formally educated and credentialed professional in a non-computer-related field with a pretty high barrier to professional practice, but a lot of passionate hobbyists. When I found the related low-ish volume SE, I excitedly poured hours into writing authoritative, well-informed, well-cited, thoughtfully worded, and concise but layperson-friendly answers. I also provided encouraging and positive, but usefully critical feedback to people that missed the mark. I knew how negative the format could be after using SO for years, so I bent over backwards to avoid discouraging newcomers with a punitive or imperious tone. People seemed to find my contributions useful because I became the top contributor in something like two weeks, and still regularly get points for things I wrote over a decade ago.

Some mod— a hobbyist with far less knowledge and experience, but a serious case of Dunning-Krueger— probably got annoyed that I was getting more votes than them because one day they started nitpicking the hell out of every goddamned word I wrote. I pretty quickly got fed up, and stopped participating about a month after I started.

::slow clap:: Well they might not have protected the utility or integrity of their knowledge base, but they sure protected the integrity of a bunch of people’s egos. That’s something, right?!

One of the biggest flaws of the site was the ability to close questions as 'Duplicate' or similar. Multiple times I would google a problem, the SO question was exactly as asked the first result, half-answers or 'Closed as Duplicate', then you click on the supposed "duplicate" and the nuance was totally missed.

The other was the 'ability to read the room.' Even late-stage SO had the 'mods' not understand that they were the first google results, and their mean-spirited dismissals were being seen by thousands of hits.

> StackExchange had ridiculously high barriers to participation, making it inclusive to the long-time users on the site, but exclusive to the newbie participants who found themselves blocked for asking questions.

I'm no Jon Skeet, but I've had an account since 2009, I answered a question early on that's had well over 1000 upvotes, which I think is 10k of reputation for that answer alone.

Yet I certainly couldn't ask a question without suffering the same. That terrible experience wasn't reserved for newbies. I learned to stop contributing pretty quickly, well before AI.

If it wasn't so controlled it'd might as well have just been reddit.

I agree there's a balance, and maybe they edged over the line, but I was consistently happy to have the following be the outcomes

1. Answers were reasonably close to correct, usable, informative (teaching)

2. Your site score came to mean something -- I once had a hiring CTO say "Oh you have some popular answers on the techs we use"

3. Progressive unlocks helped guide the path of participation -- it was clear what to start with, and what to do next as you were taught their culture and ways. It's not very popular to say in 2026, but not every culture is good and it's important to curate culture and teach newcomers the culture of the space.

I suspect I'm similar to many users, in that I came to Stack Overflow near the peak, and used it as basically a specialized search engine, without ever asking or answering a question. (I assume this is possible only if you use a widespread stack.) When something better came along, I just moved on. I hadn't directly experienced a sense of community, so I experienced (for example) bureaucratically-closed questions more as a hassle (search again) than as a betrayal.

I can totally see myself asking questions on SO even these days, but there’s a good chance they’ll lock my post so why bother.

Something about the SO incentive system created the most hostile platform imaginable.

Maybe I'm wrong, but with the advances in AI, SO was in for a major reduction in usage not matter how good they were about enabling the community and encouraging collaboration. I realize that your mileage my vary with modern AI, but the AI has an immediacy and interactivity that together are impossible for SO to overcome. At this point their best option might be to find a way to pivot to an AI based interface while still trying to find a way to reward and leverage the expertise of people. Even with that I suspect it's too little, too late.

When I realized that I'd spent more time on explaining that my question wasn't the same as another existing one than asking the question itself, I stopped using SO all together.

The graph proves the cause of their decline was AI, and not aggressive question moderation.

Ask yourself: in what year did it become difficult to ask questions on Stack Overflow? 2014? 2016? 2018? 2020? Aggressive question-closing was part of their design from the very beginning. Their high barriers to question-asking was the cause of their rise, as their primary user was never question writers: it was Google, and anonymous Google users. The whole thing was an SEO play from start to finish.

It's fun to imagine that their aggressive moderation was the "real" cause of their decline. It feels so gratifying, doesn't it? Finally those assholes got their comeuppance, because of their bad behavior!

But that's not why they failed. They failed because SEO businesses can't survive when AI answers the question directly, without referring you any traffic.

(The same thing is happening to Wikipedia, BTW, which is also aggressively moderated.)

There were also certain IMO low-value questions that really excited the SO hive-mind. I asked a question about the peculiarities of Python assignment syntax, and earned several dozen points for the question, even though no one really should have written code the way I presented it.

I liked StackOverflow for the first ten years or so of its existence, but I gradually stopped using it then suddenly quit altogether when valid questions were being closed unreasonably. At this point, LLMs with documentation in the context, issue trackers and eve the source code (if available) have surpassed SO. Now my main issue is telling the LLM to crap on my idea rather than wishing it were kinder.

> That might be an incomplete date point, so using the next most recent value 1226, StackOverflow has lost 99.41% of its activity.

The biggest problem was highlighted from day one: StackOverflow was bound to become "DeadOverflow". It couldn't possibly work because the entire notion of having one correct answer to a question in a domain that constantly evolves was broken.

What killed the site was "Ever relevant question" showing up in a Google search (pick other search engine) and pointing to a "Correct and accepted answer" that was wrong with then another answer with more upvotes but which was... Already outdated.

That's why people coined the term "DeadOverflow": the very way the site was conceived would inevitably lead to dead answers.

And people pointed that out early on. Nobody listened, many of the OGs who created that company made a nice exit.

But SO was destined to eventually fail.

The entire karma/gamification/clique of users gate-keeping was bad but the issue of dead answers / DeadOverflow simply couldn't be solved, so it doesn't even matter.

Losing 99.41% of its activity is brutal but it's honestly surprising that a concept that couldn't possibly work even survived that long.

Yeah, I think the issue with Stack Overflow/Stack Exchange is one of how too much gatekeeping and elitism tends to eventually be the death knell for a community.

True, you might want people who are more articulate or thoughtful than the majority, but if you go too hard on that, you end up putting a time limit on how long the community will probably last. People won't stick around a community that treats them like crap, and that's a problem because at least some of those amateurs/newbies will become your future experts and power users. The people scared away by bullies like the one mentioned here didn't come back to Stack Exchange once they became the type of expert the site needed. They just shared their knowledge elsewhere.

It also had ridiculous rules to enforce "quality" but in the end it was to enforce user work by convention. Like one question per question only. Nobody could just post a project with a set of questions. Nobody was allowed "stupid" questions, nobody was allowed to do in depth meta excursions, the site reeked of rigor, where a true academic would have allowed for rigor to go lax when moving away from certainty aka to the funnel stage of enlightenment. It also would not allow for grouping questions into a format thats similar to the youtube "project" format.

The worst stack overflow in this regard was meta. Most pathological corner of the internet I've ever encountered, up there with 4chan if you ask me.

I tried to answer an SO question exactly once, around 15 years ago. Someone asked a question which was covered perfectly by some OSS code I had already published, so I linked to that in my answer (while explaining how the linked code was relevant). My answer was promptly deleted, of course, for linking to code. After that I lost all desire to contribute.

> StackOverflow management alienated those users, too, by shoving AI down their throats in every facet of the site.

Actually, I thought they outright forbade AI answers? I don't know where else AI might have come in -- having an AI look for related answers instead of making users use the primitive search (for which almost everyone always used google instead) might have been a good idea. Probably wouldn't have been enough though once google started answering the questions before showing SO links.

My SO account is 10 years old. The comment if kind of liberating for me as I never got past that inclusion barrier and I never got the chance to upvote the posts that helped me most.

May the old answers keep compiling in the weights, since nobody's reading the originals anymore.

S/o's somewhat cumbersome scheme to aquire comment points to be able to answer was a awkward kludge in the principal problem of open contribution sites, namely that human slop and gamified tactics tend to kill the site. It probably was effective enough to keep things working for a long time but it could not recruit new users (not just readers) as fast as it needed to. It doesn't seem like the points based system really helped as many devs find jobs as it would have taken for the site to become a recruiting tool. It probably would have had to shift and evolve in several keys ways to survive

> making it inclusive to the long-time users on the site, but exclusive to the newbie participants

I used to look for questions to answer on my morning coffee. Then two things happened:

1. Rep chasers that rushed to answer anything with a copy/pasta from manuals (or at best semi related tutorials) showed up so there was no point or time in typing a complex answer.

2. Those long time users started downmodding "teach the man how to fish" answers and favoring "here's stuff ready to copy/paste" answers.

This was long before LLMs.

I remember some moderator having a go at me for answering someone's question (apparently the question wasn't high quality, and me helping them has encouraging "the wrong type of question" for the site).

AI is a part if SO's downfall, but I've also seen a big shift of asking for help to places like discord.

SO has always had this thing that it's a wiki, not a Q&A site for people who are stuck - I feel like people have always wanted the second though.

I am a long-time user of stackoverflow with 16k points, and even I got all my questions of the last five years downvoted into oblivion.

I still think SO was done in by the weird way they handled similar questions. They encouraged veteran users to flag new questions as dupes, even if the "original" question was years old and unanswered. Who does that even help?

Imagine if the system had let veteran users link a new question to an existing answer rather than a question, and if the asker finds it solves their problem they can accept it. At least that way new joiners would have a chance of getting their question answered.

Looking back it feels like SO was one of the first really gamified sites, and the people running it got weirdly focused on the point-economy aspect. They ran the site almost like "points" were a finite resource, and not to be handed out unless the user really deserved it.

> I'd have to consider all the ways a bully eager to use their powers might misunderstand me

Damn. Doesn’t that just sum up so many interactions (and sadly, relationships) in life.

The math subreddit is awful. Accusing everyone of asking homework questions if they weren’t formatted in perfect math notation.

Then there’s the godot subreddit. Asked 2 questions? That’s a ban.

Imagine a child learning math or game dev coming up against that.

I’d quit. Curiosity extinguished.

The godot github has one of those characters now too. Really anti new user. I worry, I worry.

No online community can maintain quality unless there are systems in place to prevent mentally ill internet addicts from gaining power over it. This should have a name. We can can call it Eudaimoniac's Law.

Anything that gives power on a basis of seniority, activity, volunteering, is guaranteed to suck very soon. There are just way too many mentally ill authoritarians permanently online for normal people to stave them off with naive good faith.

You know, there's a lot of really good data on Stack Overflow, regardless of all the issues.

I hope somebody saves it all.

as a new user i asked one question, once, in the wrong forum by mistake... it wasn't pretty. i never went back, although there were some kinder people there trying to salvage the situation :). i just figured it was for people with far more professionalism and knowledge than i'd ever have.

> but exclusive to the newbie participants who found themselves blocked for asking questions. They slowly killed the site in this manner.

i got stung by exactly this.

i saw some of my early questions rewritten because some idiot mod that had not touched grass in a while thought that some words were better suited for stackoverflow.

and don't get me wrong: i'm not talking about profanity, n-word or racial slurs, derogatory terms or other controversial words. it was quite literally stylistic and tone changing.

dumb example: i like to end my posts with something like

   thanks in advance,
   -- 
   znpy

which in my opinion is just common courtesy in a conversation between me and whoever will be kind to answer my questions. it's harmless and not controversial. and yet, some mods edited that out and left some irrelevant wording on that. my guess is they were farming points on the site.

I'm so glad stackoverflow died and I don't miss it at all.

You can even see the clear download slope starting in 2016 and (sans COVID) not changing slope substantially until about 2023. This part was not caused by AI at all.

>StackExchange had ridiculously high barriers to participation, making it inclusive to the long-time users on the site, but exclusive to the newbie participants who found themselves blocked for asking questions

This is significantly under selling it.

Stack overflow was like most of the forums in the late 90s in the early 2000s: hostile to anybody who wasn’t “l33t” hence the beginning of all the bullshit “l33tcode” mess.

I started writing software in 1996 as a 12 year-old and the sheer hostility that you would get from forums or even just reaching out to individual developers was absolutely unbelievable

I remember distinctly, I specifically reached out to Seth Robinson, as a 13-year-old kid who liked the dink smallwood game and was interested in building video game level editors.

His response to me was something like: “My rate for consulting is $800 a week.”

At no point in my 30+ years of being in software has software ever felt inclusive

I mean consider the hacker news is widely considered to be one of the most hostile communities on the Internet to new people, and had that reputation since day one

In the age of gratuitously encouraging LLMs and constant slop I sometimes miss the way in which stack exchange punished people for putting in low effort.

I recently asked a LLM a question simply out of newfound habit. I realized while reading the line that this command seemed very familiar. I had bookmarked the exact same command in stack exchange many years ago. Of course the fact that stack exchange traffic has drastically declined came into my head. As well as the fact that this was predicated on them doing all that work so the LLM could essentially scrape, steal and now serve to me in this (for now) more convenient form.

These places are ultimately transactional. Taking personal offense to someone insulting your question is something you should learn to get over. The site overall would suffer. The vast majority of traffic wasn't people asking or answering questions it was using it as a search engine.

In Google I used to put in site:stackexchange or w/e because I knew answers there were less likely to be dead ends. Yes this is because some people got their feelings hurt. Iirc there may have been specific controversies re toxicity in meta, but scoping this purely to the question and answering side I never felt my own experience on stackexchange reflected something personal or done purely out of spite. I saw it as a way to ensure the site remained valuable as a place for high quality answers. Ensuring people have to write better questions is part of that. I often wish my LLM was meaner. My first stack exchange ribbing I just learned to ask questions better. I felt a human annoyed at my admitted laziness. This was valuable feedback. Should I have went boohoo and blamed them instead?

Now we have people wanting to fuck their AI girlfriends and waste your time with their LLM authored blog. If you think the problem with stack exchange was your feelings got hurt I just worry about what road you are leading us down. Having to earn your way in is part of human society. A LLM that tries to make you feel like a genius so you keep coming back is alien to most of how humans got here. I think the decline of stack exchange is less about a change in traffic patterns and more reflective of a continuing change in culture. I'm also guilty of course. But when I was reminded of my old bookmark, I went back and browsed other old stackexchange bookmarks. I did miss the very human nature of these questions and answers and comments. Yes including the occasional scolding and bickering. Sort of like this site. Filled with humans, yet not a complete cesspool. Oddly hopeful in our present age.

That basic idea is what made SO attractive in the first place, compared to forums where you had to scroll through pages and pages of in-jokes and tangents and animated-GIF signatures just to try and see if there is an answer.

Where they went wrong, in my opinion, is in the implementation details.

It's mostly death by a thousand cuts: Requiring reputation to gain the ability to post comments, then having one's answers deleted as "this should've been a comment". Overeager marking of questions as duplicates, e.g. despite the equivalence between two situations being non-obvious (e.g. someone asks about data type A, and it turns out that it's a subtype of B for which an answer that applies to both exists; that should not be a duplicate, the fact that it's a subtype is the answer!). Endless other decisions like that, which wouldn't have taken any extra effort to implement correctly.

One feature they could've built that would have taken effort but also greatly helped against the common newbie complaint of "hostility" would've been a "newcomer track", which would've been more forum-like and guided them towards either formulating a good question or seeing that's it's already answered. In the latter case, some of the keywords that came up during this process should've been fed back into SEO so that future newbies would become more likely find the answer via a search engine despite using clumsy terms. I think they tried a simpler and worse version of this idea towards the end with "staging ground" but by then it was too late.

SO had great humans contributing to their platform, even as AI began to serve as the new SO for a lot of people.

Instead of going in the same direction of everyone else adding AI all over the place and trying to eliminate the humans, they could have gone the opposite direction and played to their somewhat unique strength of having a bunch of actual humans and providing a place that actually fostered human and authentic interactions. Instead, for some completely unknown reason (money), they chose to commodify their own platform. Smart.

There used to also be fun, and somewhat interesting questions to answer or discuss.

It quickly turned into simple questions and "send me the codes"

Quite some time ago, I would regularly navigate to SO's front page to check for new code golf questions. Then they moved those to a separate forum. I noticed this trend in other ways too - they slowly sucked all joy out of the site. They didn't want joy, they wanted to be a site for professionals, I guess. Now that AI has beat them in their last redoubt no one has any reason to visit.

Reddit is on the same track. What I've noticed is that moderators have become increasingly hostile. Reddit's AI moderation, which is designed to remove AI slop, has removed multiple top contributors I used to follow on programming, electronics, bodybuilding, welding, machining, and 3Dprinting subs. And the worst part is that Reddit site admins have no idea about this. I know a guy who reckons he can get any account banned from Reddit by simply mass reporting it using residential IP providers and OpenClaw.

Good luck trying to write any helpful posts in the community anymore, someone will come along and respond with "AI."

Yeah, SO's downfall started looong ago. The community was frankly horribly managed, and its strict "no remotely duplicate-esque questions ever" policy meant that answers to common questions just got more and more outdated as time went on. It's still common to search for something, find an SO thread, and find that the only answers are from 2013. The world has changed since 2013, answers in 2026 would be different, but because the question would be the same, any contemporary attempt at asking the same question would get marked as a duplicate, so the 2013 answer remains SO's only guidance forever.

They also had the problem that easy questions would get downvoted for being too easy, and hard questions would just not get answered because they weren't seen in time by the narrow group of people who could answer so they get buried by the algorithm. Working in something of a less common niche myself (embedded Linux), I never had questions get answered. I believe the question ranking systems and moderation policies really only worked for questions about new, popular web frameworks.

It was ChatGPT which did it in, but it could've been anything. It could've been a new group of people with some clout starting a fresh new knowledge site. People were ready to abandon SO.

I just noticed that by around 2015 it had got super toxic and snippy.

Usually I’d find answers on SO. Relatively rarely I’d ask questions but, when I did, I’d always try and follow the netiquette rules of yore, and think in terms of, if I was a support engineer trying to help with this, what would I need to know?

Because I have supported products, and we’ve all seen enough bug reports and questions come in that we can tell when someone is going to be easy to help - even if they have a particularly tricky problem - versus someone who’s going to prove more challenging.

So I had this question about Elasticsearch, and it was at a time when the documentation wasn’t great, and you were actively encouraged to go on SO and tag your question to get help.

I wrote out in detail what I’d done, where I’d got stuck, what I’d read and tried to get unstuck, etc. It probably took me 30 minutes or more to pull everything together into a coherent post.

The very first comment was from some insufferable bellend saying, “Oh, so you want us to do your work for you, are you going to pay us too?” or words very much to that effect.

Literally, WTF? Why even post that? If you don’t want to help the option to simply go away without getting involved is always available.

IIRC I didn’t actually end up finding a solution via SO and instead layered some godawful hack on top of Elasticsearch to get what we needed - because I simply had other work to move on to and I’d already spent a lot of time on the problem.

But I think that was the last question I posted on SO, and maybe the last time I posted anything on the site.

As the years wore on I simply started finding it less and less useful, with often incorrect answers marked as accepted and - if you were lucky - the correct answers marked might be buried further down.

And then there’s what they wanted to charge for job ads versus how effective those ads actually were - again, this was better in their earlier years.

SO started out well - genuinely a breath of fresh air - but as time went on it felt like they thought their model was the last word in online help forums and they didn’t want to evolve to address its flaws, even if that had just been dealing with the toxicity, and the karma farming.

And so this is the result - a site that, like the dinosaur in A Sound of Thunder, is dead but perhaps hasn’t realised it yet - and, at this point, the way I feel is simply good riddance. It’s a shame, but - as you said - they did it to themselves.

>"no conversation please"

Good for training data I guess - pure Question and Answer. Maybe they knew the platform would die so decided to optimise for that

> SO did that all to themselves when they decided they didn't want a community to form

SO did develop a community in a way, but it was primarily the gatekeepers and rule enforcers adopting positions of pseudo-power. They liked using the sites’ rules as a way to control conversations and downvote questions.

Every internet community I’ve interacted with that builds up a lot of rules turns into this eventually. It becomes an attractant for users who really like memorizing all of the rules and deploying them on other people.

Are you saying that the decline of SO can be explained by that and not AI?

I don't buy it.

I mean, that's literally what the site was designed for. It was not designed to be a community. It was designed to be a Q&A site.

I don’t think we need to blame that sale. The same steady decline had been going since 2016. Itms clearly there in the graph, but everyone trumpeting the ChatGPT angle conveniently ignores the preceding 5+ years of continual decline.

I didn't know that. Good to see they cashed out in time.

This is the more valuable take. AI simply accelerated an existing condition.

Do you mean that curious growth spike in mid 2020? If so, can you think of anything else significant that happened in mid 2020...?

I see people talking about the negative experiences, and I'm sure they are real, but I also had some very positive experiences.

I remember being amazed that some internet stranger took the time to understand my question and provide some great solution where I was stuck. It gave me a little encouragement and social connection as I plugged away on a project alone.

I miss that feel good human connection when an LLM can quickly get me an answer.

But the LLM will confidently give you a wrong answer and then waste three hours of your time going down tangential rabbit holes trying to sort it out.

I never had an account, never asked or answered a question on SO, but found the answer I needed there plenty of times and got on with my work.

It is curation process, so when you search you are not overwhelmed by 100 identical answers.

Being stupid in this case is irrational self-(mis)-perception.

Probably they really meant to say you are lazy and shift work on mods.

Sometimes your question was simply visually similar to another but conceptually very different, and it'd get closed for being a duplicate anyway.

Then you have to re-ask it, now with a couple extra disclaimers spelling out that indeed you did use the search function but no, the other visually similar question isn't actually the same as yours.

Then you'd get maybe 2 comments and -2 in downvotes.

I feel like I've seen this comment before...

Even before SO most of the forums were the same way. You had grumpy ass holier-than-thou guys with 10,000 posts shutting down your questions before anyone else could answer.

The whole damn business model of a forum was to provide a solution to people that didn't want to / didn't know how to RTFM, but everyone was toxic as hell toward one for not wanting to do that.

> The graph actually peaked in 2014. That's a decade before AI became a thing while the Software engineering workforce grew a lot since then.

That's obviously because initially there were a lot of basic newbie questions to be asked, and those continued to be relevant in search results, so the amount of new questions went down over time, as there were fewer relevant unanswered questions left.

There still are worthwhile questions to answer! People just don't ask them on SO because SO chased away everyone who wanted to ask questions, long before ChatGPT.

> This is similar to the evolution of Wikipedia, except the format of WP allowed it to transform into a feudal dictatorship of nerds who feel like they are deciding what's true, and they can get off on that.

Literally describing how academia has worked since time immemorial.

I remember a time when people were posting their SO link and karma on their resumes. O how have the times changed.

check the graph and superpose the ai adoption curve, you're right to be skeptical

It definitely seems like politics ruins everything. Nerds once thought they'd transcended politics and then discovered they hadn't.

"Politics" being another word for "game theory when it's about humans"

The graph shows questions, at some point they saturate, 90% of the stuff is answered. New frameworks contribute to the majority of the new questions.

for a lot of stuff it just made more sense to ask on the github project's issue tracker.
