This site enables you to check out the areas of a city that interest you the most. Basically you provide information about your likes and dislikes and the site will generate a "heat map" of the city for you to visit. So if you like art, they will generate a map of locations of museums and art galleries. Great for exploring! You can then always go back and fine tune your settings to get a even better map. However, at the moment, they only have 2 cities - New York and Philadelphia. So unless you are staying or planning to visit these two cities, this site is pointless. But the basic idea is quite good. Hope that they will add more cities in the future.
