The recent press release widget maker RockYou issued, stating the widget site is #1 on Facebook, received a lot of press.

But does RockYou actually sell ads for any of their pages?

Uncov, the Web 2.0 deflating blog, typically highlights that problem. (Of course, something tells us the Uncov gang might pillory a Facebook Application development firm like ours as well). But regardless of the tone, the point is sound. Will anyone start aggressively selling to real companies on Facebook? Or will the community wait for traditional players to saunter in and take all the business for themselves?
