I first installed an XMPP server back when it was Jabber over 20 years ago, and I remember chatting to people on Google Talk, before they decided to do their own thing. Having just installed Prosody ( #XMPP) and Tuwunel ( #Matrix) servers, both of which are excellent, I am personally of the opinion that XMPP is a lot more sensible.
