Ok, I think it would be more effective for me then if you started with what you cared about and why you cared about it.
So your frustration is with blogs, written by people who are paid in proportion to how angry or scared they make their readers, using Facebook as a stalking horse to drive page views? I can certainly understand if that is the case, why not say that?
Instead you said this : "The root of this problem is core to the DNA of Silicon Valley types. "
You didn't say the people who blog about Silicon valley (heck they may not even live here) you just said "Silicon Valley Types" which covers a lot of people, many of whom like the folks who founded Y-Combinator probably don't think of themselves a collective that "These character flaws are why we (the collective known as Silicon Valley) thought that a company with piss-poor revenues could IPO at an overpriced valuation, and have the same fan fare for over-valuation as it did in the valley. "
You impeach yourself by calling Facebook's revenue 'piss poor', it isn't, and then accuse "us", those who live in Silicon valley, with 'over valuing' when in fact that was the work of a collection of banks, based primarily in New York city.
I would love to hear passionate, pointed, editorial about how bankers and journalists unknowingly (or perhaps knowingly if you are the conspiracy type) in the creation of a value perception, but its a hard case to make here. There were literally years of trades in FB you could look at from SecondMarket, and there are a number of pretty cogently written analyses of their business model and the potential of their business. The Techcrunch whine about how it's not the bubble they were hoping for, and were so sure it was, will pass. And a lot of young people who weren't here for the dot com fiasco (or at least they weren't watching it closely) could learn from clear insights about what really makes a company worth a billion dollars to investors, or worth a hundred billion.
You could do that instead, start from what you care about and bring us along as readers, telling us why you care and perhaps educating us as to why we might want to care as well. That may or may not be effective, but it certainly would be less snarky I expect.
