The article makes a big, big mistake. The same proportion of black people left myspace, but if you are white on facebook, and your friends are mostly white, then facebook looks like a white place. Same with blacks - if you are black and your friends are mostly black on facebook, it looks like a black place.
Myspace looks "ghetto" simply because there are more minority bands, and so more minorities still maintain active facebook profiles.
