I occasionally talk to internet friends via Skype, haven't done it in a while though.
Nobody on the internet has seen what I look like though. AND YOU NEVER WIIILLL!
I don't see the point in doing webcam chats with internet people.
I could understand you being uncomfortable talking to people you don't know in real life, but you shouldn't be worried about what your friends think of you while they're talking to you via mic/webcam. After all, they are your friends.
