Google & XMPP standards foundation develop the very useful Jingle XEP, so XMPP is linked to the history of Google Voice and whatever Google Talk/Chat turned into, maybe somehow inspiring Google Meet? Jingle was also inspirational to WebRTC signalling.

Its biggest issue is adoption because it's very solid otherwise and even supports stuff like screen sharing.

i set up a xmpp server a few weeks ago for agent orchestration and agent to human workflows. hadn't inatalled ejabberd in a very long time but feeling right at home.

Are there any XMPP clients with the UX and privacy of Signal?

All of them seem to look like they're from the 00s!

And I haven't used XMPP for about 20 of them (sadly)

I think of Matrix as a protocol + client/server suite; an open standard with official software backing it and a number of parallel implementations. When I wanted to stand up an independent server that could do most of what Discord does for communities, Matrix was the easy find. Encrypted chat, e2e support, and encrypted voice and video chat rooms with screen share.

I admit I didn't research "XMPP-based discord alternative" but maybe that says something about the ecosystem's health.

If only they had avoided XML. XML drove away a lot of people who would otherwise have been interested early on.

(I once found myself in the same meeting as two of the people who made the mistakes that meant you couldn’t just pipe stuff through an XML parser and hope it worked. I tend to speak my mind)
