I used to use it, the later telepathy/empathy stuff on Gnome as well. At some point I started using Facebook, and it obviated the need for a chat client running all the time. Work places seem to be enamored with Slack these days.

Bummer, can't even remember my old logins. Not ICQ nor MSN, Jabber on Facebook doesn't work any longer, might be able to figure out the Yahoo, hmm.
