What Is a Foursquare Friend?
Foursquare is the latest Big Thing in the social space, following in the footsteps of Friendster (RIP), Myspace (nearly RIP), Facebook (world’s third largest nation) and Twitter. If you’re not familiar with it, Foursquare is a mobile application that uses GPS to know where you are and allows you to “check in” at places you visit. Friends can learn from the application where you are and on the spur of the moment decide to pay you a visit. (Is it obvious that the application started with young people in New York?)
