facebook...no, it'll be too hard to find each other, cuze once you are put in a network, i dont even know how you get in touch with people from other countrie...requires tons of connections, or an msn.
facebook isnt bad, but its not that great for chattin to random ppl, its mainly if u have ppl on ur friends list then u can chat n see them well their pics n shit like that it has no forums like bolt
with forums like "would you like the person aboves you's belly button?"
"would you have sex with the person above you?"
"would you finger-fuck the person above you?"
