Does anybody actually believe that people will continue to use ChatRoulette? It seems like a novelty that will soon be forgotten.
Getting the "freaks and the fuckers" off the site doesn't prevent the service from doing something new.
I think the idea of being connected to people one-on-one is appealing and don't think the appeal will fade.
If only if there could be more serendipity with who you are connected with... I think that is an interesting opportunity right now.
