Yes and No. I like to chat with a "normal" person..a sane, full cognitive functioning gal or guy. But I have to be honest if it's a person I don't know my stomach instantly does drop..but it's happened before and I was quickly proven that my fears were wrong when the person turned out to be really nice :)
Not really. I've had one user say 'hi' over meebo and just as quickly dissapear. And sometimes I'll get random messages from guys claiming to be girls or something idiotic. After that, I set my apparently troublesome profile to private and that stopped.
