OK. Now I'm signed in. Now what.

Ok, I went to Meebo.com and signed in so my widget says I'm online. Who am I supposed to talk to with this thing? Who else is online and how do I know if they are or not? I suppose I will have to go collect everyone's online widget name thing and add them to yet another list so I can see when they are online. I think I have more to learn about this and I'm signing off now because there isn't anyone to talk to anyway.
