Which instant messaging tools do you use?<p>Twitter (not IM but fulfills some of the same functions)? Google Talk or some other Jabber-based service? One of the old-school networks like AIM, ICQ, MSN, Yahoo? IRC?
I'm using Kopete with my Ggoogle Talk account. I also have an ancient ICQ account (from ~1998?) lying around but I hardly use that at all. gtalk's gmail integration is great for when I'm on the go.<p>I'm starting to get into Twitter, although none of my friends use it.
