What are the diference in relationships on Facebook and Myspace?

[Ghost]

I've noticed it's a lot harder to meet old friends on Facebook. Many will go ahead and add you, but they never talk to you. Myspace I found a girlfriend for a while who lived in my town. It has lost a lot of popularity. But I still think it's good. I've just now blocked anyone who is not a friend from my profile on both places. I don't want my mean uncle spreading lies about me.
