Agreed. It seems human beings are really bad at mathematics, we could spot a quality, but not the quantity. In Spain people thought houses near the beach were always in demand by Europeans because of the good weather(quality), but failed to understand there is a limit to the money they will pay for it(quantity). With facebook people could see the value it gives to the world witch is real (quality) but overstates the amount facebook is going to give back. facebook is a pyramid scheme designed to make uber-rich the current shares holders(Zuck and employees hold near half the company stock), witch is great for them, bad for those that payed the overprice.
