Would you sacrifice your friends for a free burger?

Did you hear about Burger King’s recent “Whopper Sacrifice” Facebook promotion? The promotion attempted to get Facebook users to “sacrifice” ten friends in exchange for a coupon for a free Whopper.

Facebook didn’t like the promotion and Burger King had to take it down after one week, but only after 234,000 friendships had ended.

Here’s what happened. Burger King launched the “Whopper Sacrifice” micro-site, where Facebook users could install the Whopper Sacrifice Application. The application allowed you to delete 10 friends in exchange for a coupon for a free Whopper. According to statistics, over 89,000 Facebook members added the application. To add an interesting twist, the friend’s profile photo was set on fire through animation once you chose to delete him or her.

Are we seeing a brand-new way to use Facebook? Will others try similar stunts?
