Ever wanted to know just how big facebook was? Well, if you've read "The Facebook Effect" or have seen the movie "The Social Network" you'll know that it's around 500 MM people. Think of it more like a global democracy with it's own digital ecosystem and each member is a citizen. It could even be described as the premier global business that now is creating it's own worldwide currency with "Facebook Credits". Use these little credits that you charge back up with cash for things like virtual goods, Marketplace items and more. It truly is scary just how easy it is to monetize 500 MM people.
