jabber (gtalk) client

Google Talk client from Google sucks. I didn't find any way to disable pop-ups so it keeps switching to desktop whenever I receive a new message, which is horribly annoying when playing games.

Pidgin sucks, as it does the same thing. I also heard that it takes huge amount of RAM after several days of use under Ubuntu (mem leak?).

I'm now using Psi and so far like it.
