I'm kinda with you that the mental health(ish) framing is a bit disconcerting. But it's hard to guess what the audience really is, if there is one. ChatRoulette was a neat idea that disintegrated into a bunch of guys showing their johnsons, so maybe that without video would get rid of the riff-raff and let people go in and have actual conversations. Or not. The truth is, though, there has not been a lot of experimentation in one-on-one, non-group, non-hierarchical stuff in awhile. Apart from its clothing, I don't see why this is any different from a dating site or something.

Personally I don't like talking to disembodied voices (why I don't play multiplayer games with random people) - and I live 5 minutes from a dozen bars if I feel like meeting strangers. But I can't see how it really hurts, if it doesn't become polluted with griefers and perverts.
