Dealzmodo: Papa John's Facebook Friends Get One Free PizzaSIf Papa John's thinks that they can buy our Facebook friendship by offering us a free medium pizza with any online order...they're completely right. The free medium pizza is a new promotion to generate social networking buzz, and 10,000 users have already signed up, probably rubbing a collective hundreds of gallons of free garlic sauce all over their bodies as we speak. We'll be with you soon, smelly friends. [Business First and flickr]
