Technology equities have highly variable price to earnings rations because of the expectation of greater growth in the future. This expectation means investors are effectively speculating about the future growth of the company, rather than making decisions based on classic quantitative methods like you would apply to an older company in a better understood industry. Applying these methods ignores this dynamic and also buys into the myth of the quantitative analysis that's so appealing to mathematically minded geeks like ourselves.
I submit that the only thing posts like these really accomplish is letting the author stroke his or her by using big words and apparently clever concepts, while simultaneously making it clear that they're misunderstanding the market.
