I just heard about RetroAIM. Which is a way to use AIM (AOL Instant Messanger) in the modern day, running your own servers.
That’s great, I used ICQ a lot back in the day.
Wasn’t AIM just using XMPP? (It’s been a while since I looked at these things).
Still neat. AIM was impressive for the time, I even ran it on Android circa 2009. Frustrating that things like AIM/XMPP got supplanted by SMS, then things like WhatsApp, etc got in when we already had better with XMPP!
