I started a dozen conversations. In most cases the person was looking for something specific that I wasnt and the conversation ended after 2 words. Perhaps some basic bio info and filtering if you dont actually want totally random?
Then loooong waits to find someone. I think the "try again" never connected me with anyone.
There are several other random chat apps. Ive lost some faith in techcrunch to identify noteworthy apps worth checking out.
