https://dotdot.imIt's an online chat room where you'll find a small group to chat with (around 10 people) with the idea that nowadays it's hard to have a "meaningful" conversation with people in social networks.
It also does something I haven't really seen before which is showing what people are typing in real time, to help make it feel more "real time"! Come try it :)
If you come back it'll try to match you with people you have met before, so that even it became popular it would "feel" like a small community of people.
Still trying to work out the user experience to make this work though, which is why I haven't done a proper launch
