And ALL of the value or worth of FACEBOOK is based on advertising or potential advertising. Facebook creates or makes no tangible product. The income is far from any tax liability figures quoted. Most of the value is "potential" value. Most of the worth/growth of the company will be speculation, rather like the tech bubble, or beanie babies, if it will sell to investors. The only thing it creates is advertising potential through users, if it sells to investors some will hit the lottery,most won't. ear
