The word "efficiency" appears 20 times in this article. Yet not once does the author explain where all of the inefficiency - the layers, the fat, and the lethargy - came from. Nor does he explain the logic of culling employees now.

These are not the words of someone who has learned lessons or who is interested in telling the truth.

So here's a hypothesis: Facebook is not a "technology company," it's an advertising company. And spending on advertising has cratered as businesses everywhere have pulled in their horns in response to their own falling revenues. Facebook lived large during the fake boom. It hired way too many people and a built a bloated, middle-heavy organization that is poorly-suited to the task ahead: taking back territory it's lost to smaller, nimbler competitors. Facebook management bought the economic lies being told hook, line, and sinker.

The party's now over and Facebook faces major headwinds, including savage competition, declining revenue, and the aftermath of a hiring orgy gone wrong.
