social networking sites

First social networking site was Classmates.com, started in 1995. The interface was bare-bones, but the idea was powerful for the time.MySpace (http://www.myspace.com) is the largest social networking site (in terms of members) and basically has the same model. Facebook (http://www.facebook.com) did almost exactly the same thing, but focused on college, then high-school schools, and then alums (open to everyone now though.
