Look at all the biggest companies in the world, they are all based on the internet. Look at what they are selling: nothing. Facebook has no product. Airbnb, the biggest hotel chain in the world, has no hotels. Uber, the biggest taxi company in the world, has no taxis whatsoever.
PS: For those who didn't get it yet: You are not facebook's customer, you are its product.
