As seen by the list below, the most popular tier of custom user channels still has everything to do with sex -- indicating that the main usage of the site still hasn't strayed too far from its roots as a place for perverts. Conversely though, the ability to set up custom channels could be a promising solution to that perceived problem, giving users the ability to cordon off video chatrooms for theoretically less salicious purposes.
Likewise, location-based channels taps into a trend that's all the rage these days as sites like Foursquare, Gowalla and others duke it out for the title of most popular checkin service. Depending on the scope of the region sizes, which are sure to be tweaked over time, Localroulette could perhaps come closer to cultivating some of the spirit that old bulletin-board systems were infused with back in the earlier days of the Internet. For now, users are routed to a location automatically, but we could imagine a future where visitors could location hop and get video chat experiences from around the world.
Hints at a potential business model start showing up with these changes as well. We could imagine this structure easily accommodating a type of freemium service where companies and groups could opt to pay for branded channels. It seems like a reasonable expansion to the overall service without overcomplicating the uber-simplicity of Chatroulette's videoconferencing model.
What do you think of Chatroulette's new features?
