An interesting idea to say the least. You might also want to stop by furtopia's IRC and possibly hang around the life problems channel. It's usually deserted when I'm on but I suppose you could do that if some folk feel shy about talking to someone on the phone.
I know I enjoy talking on the phone but don't like discussing my problems except through text chat. It seems impersonal but I like it that way, it can help me remain detached.
