Facebook Growth By Country and the Slowdown in App Usage

Facebook's apps have annoyed me into not using them. Typically I get invites for apps that look like:

Test your movie knowledge with this quiz ...

You take the quiz, and then it won't give you the results unless you spam all your friends with an invite to the same quiz. With the amount of spammy stuff on there I am not surprised if the app usage tails off ...

the only 3 things that will consistently bring users back: 1. utilitarian value 2. entertainment (fight the habituation battle or pace your users?!!) 3. community (and let's face it - "let's all sign up there instead!!!" is almost as easy as pie nowadays)
