I don't think you can say the same for facebook. Very few people will pay for this thing. I'm willing to bet that their own internal research confirms this. Facebook's biggest issue with regards to profitability is not so much that they need to find ways to make money, but that they need to find ways to make enough money to pay back all the money they've already used. They are leveraged to a crazy degree, and seem to spend like drunken sailors. They've got a huge workforce and have innovated little since launching their "platform", which has been all but abandoned - from a user perspective - because of abuse.
They've got a leadership problem in my opinion. And that's a hard problem to solve.
