I’ve tried Meebo, but wasn’t impressed. Great to IM through a web interface, but you have to be logged onto Meebo. I saw folks talking about Plugoo on Dig_Ref and thought I’d take a look. Seems very cool. It connects a web based IM to my IM client (adium) on my desktop through AIM (or ICQ or Yahoo! or..). If I’m online give it a try and say hi.
