andrewman327 writes "The popular college social networking site Facebook recently unveiled an API open to developers. Programmers can utilize data from profiles, friends, photos, and events. An early example is FaceBank, which allows students to keep track of how much money they have lent their friends. The appeal of this platform will be slightly limited, however, as both developers and users must be members of Facebook. Facebook is the 60th most popular website for American websurfers and recently allowed high school students and employees of certain companies to join."
