I used it yesterday, via Pidgin. I’m rokejulianlockhart@xmpp.jp
. Why else would I have referenced it? Don’t tell me what I’ve done. That’s not a way to have productive conversations.
Regardless, I can’t provide any more technical insight than that - I know solely that the clients provide so much more functionality that irrespective of the protocol, it’s better in practice. Fedora, openSUSE, the Bundeswehr, NATO, and Beeper - all chose Matrix over XMPP, not least partially because of Element (which they also all chose).
No, I had not. That’s certainly novel.
