Same is also true for facebook notifications. I recently got a notification that said "Blabla has given you a free movie on Flixster." Now, I am actually down to try a service that gives me a free movie rental. But because of my past experience with fb notifications, I immediately hit 'Ignore' thinking it was another gimmicky spam.

Facebook has focused so much at Games that I think it will begin to hurt them when more well-known businesses in other categories try to use their platform to distribute offers.
