If you didn't catch Zuckerberg's 60 Minutes interview where he stated his desire to have Facebook become Internet infrastructure watch it sometime. Facebook is making an old play. Miners didn't make the money in the Gold Rush, but the Sears and Roebucks of the times did just find thank you. Miners are content and Sears is infrastructure in this example :).
With Facebook's domination of the "create an account" with Facebook option they take one step closer to Zuckerberg's stated intent. Nice if they could sell some shovels and axes too, but can't have everything.
