Facebook is Introducing Subscriptions and Ending "Credits"

Facebook is adding subscription capability for Facebook applications and ending its use of "Facebook Credits," its virtual currency.  Instead, Facebook will switch to payments denominated in local currencies. 


Some might argue the move is designed to make it easier for Facebook applications to integrate with other apps for purposes of shopping and commerce. "Real" currency is the coin of the realm for e-commerce, not virtual currencies, generally speaking.
