Last week there was lots of discussion about the claim from ComScore that more than half of MySpace users are over 35. But more recently a few bloggers have taken a closer look and concluded that the data is being misinterpreted: the unique visitors have gotten older, but the users (people who sign up and create profiles) probably haven't, or at least not to such a degree. These people could be searching for bands on Google and come across a profile on MySpace Music, or read about MySpace in the press and stop by the front page. ComScore's methodology is also being questioned: they use software installed on computers to track usage, and it's being suggested that teens won't necessarily log out of their parent's accounts before going to social networks. That could skew the data for all the sites: Friendster, Xanga, MySpace and Facebook.
