We're trying to focus more on "What's fun to do?" (aka a city guide). We hope to integrate Yelp and other review sites as part of the tabs where comments are (if they'll let us). We're more trying to compete with TimeOut and other city guides.

I like it. The only problem is getting people to submit content. You may want to focus on one tech savvy city, troll Craiglist for events, go to REI to get events, go to StubHub for events, etc.

This is an issue we're trying to address. We figured we need about 5% of our users to post stuff. We've also made it absurdly easy to post where we get the images, tags and maps for you. Try it!
