Web 2.0 winners

I was looking around Yelp and was suprised to see that a lot of the NY stuff was in Brooklyn. Yeah, that's right. Alas, nothing about Queens. As for Lulu, I was suprised that it wasn't about reading books, but more about publishing your own. That's cool and all, but seems like it should be under a different heading. I realize they also sell books, but the homepage isn't well geared toward buying books.
