I used to hang out in the chat a bit but it's usually just too manic for my tastes. If I want a "nightclub atmosphere" (or at least the internet equivilant of it) I suppose I'd drop in, but overall I just don't think it's me.
Having said that... I met my lady there. She's not that big on chatrooms either, and was only in there for the second time ever, while I was only there at the time out of boredom. Go figure. Life is strange.
