I'll say it again... Facebook is a Communications Platform

Alley Insider is still focused on Facebook selling marketing data which I think will scare away users:

"Here's what Facebook should do instead. First, extend Facebook Connect to online retail stores. Second, analyze users' spending behavior and activity on Facebook, make that data anonymous and sell it to marketers. Third, turn on personal ads and charge more than the New York Times does -- about $48/week."

The personals idea could generate cash for them, but it still is putting a barrier between people connecting (ie. you have to pay in order to see someone's profile). I just do not think it is in the spirit of the service. People are allowed to ask anyone to connect and People are allowed to accept any connection. At what point does Facebook want to get in the way of that process?

Uninterrupted, private, spam-free communications... that is the value Facebook offers. They provide free, light-weight web communications and should expand into further, premium communications - Video Calls, VoIP and Mobile.
