Great idea. Love the colors (even though usually I hate light-on-dark). I wonder, though: is it possible to ask Facebook to query for the intersection of users at my school and in an arbitrary (for instance, "hacker news") Facebook group? (I wouldn't be surprised if it's not, but it would definitely be an excellent feature for Facebook to consider.)
