Facebook's users aren't valuable to advertisers because they're "fragmented" (i.e., no common interests). That's why the only ads you see on MySpace and Facebook are for dating sites and T-shirts. The bigger money is in selling very specific advertising (for example, selling HD-TVs to fantasy football fanatics).
