What better way to play with the notion of what really is an online friend than to judge their worth compared to ... a hamburger? And Burger King is showing no mercy, though some good humor, by having the application send a message to the deleted friend to tell them that this person valued a Whopper more than their friendship. The app also acts as a counter, reminding the user how many more friends need to be evicted before they get that free Whopper.

The news of Burger King's funky campaign comes just as that it has hit a milestone of 150 million users. noted Wednesday that while the social networking site has 150 million users, nearly half of them use the network on a daily basis.
