One large, hold the spam: Free pizza if you friend Papa John on Facebook

Abbondanza! Papa John's is so eager to get new friends on Facebook that it's sending a code for a free medium pizza to anyone who becomes a fan of its group page.

Between 3 p.m. and 10 p.m. Monday, Papa John's group went from around 10,000 users to nearly 124,000. That's gonna cost it a lot of dough. The deal, which will be sent out via the group's updates starting Wednesday and requires the purchase of another pizza, ends December 1.

The Pizza Wars are really heating up. Most of the big pie spinners now allow you to order on their sites, through widgets, or via text messaging. I find it more pleasurable to order Domino's by its website than to actually eat the stuff. Watching that little status bar teasingly track your pie's progress in the minutes before your doorbell rings is a lot saucier than the food.
