Is MySpace mascot Tom Anderson, the default friend added to everyone's profile on the social network, 32 years old, as his profile says? Or is he older — 36 or 37? TechCrunch's Michael Arrington says he's heard Anderson is actually 36 or 37. Which would hardly make Anderson the first person to lie about his age on MySpace, if true. Still, this rumor is doubly painful for MySpace and News Corp. First, it reminds people that his true age is just the least of the mysteries surrounding Anderson. And second, it points out MySpace's fatal flaw as a business. Unlike Facebook, which forces users to tie their online identities to real-life groups like colleges or workplaces, there's no reason for users — or advertisers — to trust anything in a MySpace profile.
