The author seems really angry at Google and clearly wants to demonstrate how much smarter he is in comparison to the rest of the organization. Nearly every sentence is drenched with this sort of stuff:

"It hits all the notes that a facebook clone merits, and adds a few points of distinctiveness that are genuinely compelling, sure--but I don't find it all that interesting, personally."

". I listened politely, all the while rolling-my-eyes in secret at their seemingly implausible naivete."

"I laughed, disbelieving. Facebook has a hacker culture, they're only a handful of engineers, and they develop with quick, adaptable tools like PHP."

This post isn't about Google+ or Facebook. This post is about "Look at me, I'm so much smarter than my old bosses"

Something clearly upset him pretty significantly at Google. I'm not sure he's got a clear point of view on this.
