Never used myspace, but I don't doubt they were simular as they were simular websites.
I'm just saying facebook *does* have a lot of power, and has changed a lot.
Myspace was like, the stuff until Facebook came along.
Had it not been for Facebook, Myspace would have been Facebook, but everyone though fb was generally better.
Facebook is influential for friends and family, hence why so many people have one.
Naturally, I just use mine for homework assignments, since I could just talk to people at school.
