The Long Tail is Alive and Well on Facebook

Tim O’Reilly looks into the reality of the 5,000+ Facebook applications that developers have created:

“The good news has already been widely disseminated: there are nearly 5000 Facebook applications, and the top applications have tens of millions of installs and millions of active users. The bad news, alas, is in our report: 87% of the usage goes to only 84 applications! Only 45 applications have more than 100,000 active users. This is a long tail marketplace with a vengeance — but unfortunately, the economic models (for developers at least, though not for Facebook itself) all rely on getting into the very short head.”
