Also on TheStreet, contributor Jonathan Heller wondered aloud about the Facebook IPO in clear-headed and ultimately indifferent fashion: The bottom line is that I don't understand the math. I don't see how Facebook is worth $100 billion ... The common thread with all the IPOs I've mentioned is that each of the companies offers useful products or services, but there's a disconnect between their utility and the valuation of these companies. That's not uncommon. IPOs often generate investor interest that drives prices far higher than the company's true value. Sometimes it takes a while for the dust to settle. I would ask Heller to throw conventional ideas about valuation out of the window. You're bound to drive yourself certifiably insane if you don't. First of all, as he acknowledged, this is a multi-billion dollar company. And, as Fuchs nicely described in his video, social media is in its infancy. Mobile advertising has barely begun to bloom. If GM wants to hop off of the bandwagon already, so be it. The folks who are hysterical about this development do not get two key things. First, advertising comes and goes from businesses that rely on it every day of the week. You probably have clients come and go consistently in your business. It's not uncommon. Heck, when I worked in radio I was personally responsible for blowing six-figure accounts off of the stations I yacked on with the most innocent slight of tongue. Second, Facebook does not have to be "effective" as an outlet for advertising in the traditional sense of the word. Chances are GM dealers are not going to have many customers walk into a showroom, sign on the line that is dotted for a new truck and note that Facebook referred me. It does not work that way. Facebook will not directly sell a big ticket item like a car for you. If you need them to, it's doubly obvious that you just do not get it. Ford ( F) spokesmen Scott Monty honked the horn square on the steering wheel when he said: You just can't buy your way into Facebook. You need to have a credible presence and be doing innovative things. Individuals build their brands on Facebook every minute of every day. Your life could suck as bad as a Chevy, but nobody would know it. You use Facebook to craft the identity you wish reflected the real you. You're not selling anything. Your putting together the portrait you want to put in your "friends'" minds' eye when they think of you. If GM really thought Facebook is not effective, it would have saved a few million dollars more and pulled its page from the Web site. It did not do that, though. GM needs Facebook more than Facebook needs GM. The stodgy old company simply made a feeble attempt to prove a completely insignificant point. Facebook is overvalued. It's too big for its britches. Zuckerberg should start wearing a tie again. Whatever.
