Tilt!!!

Chatting helps me in my quest to stay pretty tight pre-flop. Since you are folding quite a few hands, chatting helps pass the time.

I agree... you can also pick up a heap of information about players (e.g. if they say "folded my queens when the ace hit and you bet into me"). Plus I think it's kind of cool to put a personality to the name.
