Social status on social networking

This is an interesting article I just read about how your social status (wealth, race, job-type, education) can often be determined by which social networking sites you use. They argue that Myspace is the more blue collar site as opposed to Facebook, Twitter and LinkedIn. I remember around 2004 I signed up for Myspace and thought it was pretty cool, but then got Facebook and kind of phased out Myspace, not sure why, I just didn't like it much and I think I fit into the class they are talking about so it's an interesting debate or point to raise.
