Social media bubble mostly counts towards company's that are ipo with no income or no means of making any. Such as pandera and link...Now if link only 10 percent of their company available and that brought it to 79 the first day. Now what would facebook come through on day one??? They are making money, is their a bubble forming of course. Does it mean all companies?? NO! What makes you think that facebook will even ipo?? This company doesn't need them to they are still making money per share.
