This is a ridiculous assertion because Facebook usage patterns do not follow a power law. As a simple calculation, Facebook has a 5000 friend limit so all 100,000 "superusers" would all have to be hitting up against this limit and all have completely mutually non-overlapping friend groups to reach out to the 500M current Facebook users. This is an absurd contention.

In reality, there's approximately 250M regular users and 250M light users which means each regular user would only "earn" $10 if Facebook brought them on as employees. That makes this a significantly less compelling argument.
