Yelp is collecting a ton of data from those who take the time to rate and review restaurants, hotels, etc. In the same way that Junglee/Amazon revolutionized how people find books and other goods by using collaborative filtering, I can see Yelp (at scale) achieving a similar aim. Right now, the "missing lens" is the ability to filter reviews and ratings based on similar interests. I would love the ability to use Yelp to filter reviews and ratings based on how similar other reviewers' scores are to ones that I have entered. This is something that nobody seems to be doing today. Ultimately, this collaborative filtering might prove even more useful than reviews provided by my friends.
