I like the site's design: simple and functional. However, getting the ball rolling on this kind of platforms is the hardest part; it would only work right off the bat if it was already populated by a considerable amount of users, which is, of course, impossible. But that's the kind of conundrum an app that relies so heavily on the network effect has to deal with.
This is a third time I remember seeing you post this as show HN. Have you read the rules? Did you have a big update lately?
