Occassionally, I come across something that is soo good I think twice about recommending it to people because I don't want the site to get so busy that it becomes un-useable. But this thing is just too good to be quiet about.
Go check out meebo. Check it out right now, and I mean right now - you won't regret it. It is like Trillian, but over a web site using some of the best Ajax since Google Maps.
