Dayo Olopade has a provocative, but I think wrongheaded piece about the migration from MySpace to Facebook:
MySpace is no longer cool. As a matter of fact, its number of users is now one-half the size of rival Facebook. Is this because MySpace is too black for the rest of America? Teenage Internet users may hold the answer. High-schoolers report their use of the social-networking giants along racial lines—MySpace is seen as “black,” while Facebook is “white.”This is the first I've ever heard of this phenomenon. I'm against segregation in all its forms, of course, but the reason myself and most other people abandoned MySpace isn't because it's "too black," it's because it's horribly designed, awful music plays on every page, and Facebook figured out how to do the same thing only much better.
