Everybody is an idiot on concept of some persons, someone have copied the model of "mercado livre", thinking "that will work", what he doesn't know is the following, all of this is scam, you never buy nothing lower than the minimum price estipulated to amortize the investment, but "there are persons that will believe on such shit", there are believers for all, another interesting fact who rules Goldman Sach's maybe is Microsoft, talking about "plant", the problem i guess was the following, too many histories planted, the interest naturally decay, maybe also an interest to keep things "as is", while MZ is the owner the only persons that he need to give some report is who he took the money.
If he put the thing on Market Share, then he will have to deal with something called "board of directors", composed by economists, lawyers, gurus, all of such persons will want to take a part of his happiness, infect Facebook can have many usages, mainly a super giant company of 100-200 millions of users, that if well coordinated can beat any company in world, it is just a matter of time and inject the applications one by one.
If he put the company now to sale, for example, the investors that represent competitors, will force him to not do nothing, problems that was checked with google, investors increase the share price then the company was lead to a check, obligated to assume unnecessary risks. That is why be "poor and clean", and just watch, who get fucked first.
