I disagree with the notion that "those who want it [Facebook] already have it..." In fact, there are billions of users that don't have access to Facebook but would benefit greatly from it. Many of these potential users have 1/2G mobile phones, with little or no access to a PC. Much of what Facebook needs to do to achieve growth targets will be extending it's platform to these users by creating a consumable experience on such technically limited devices. That takes innovation.
