Secondly, Google has made it pretty clear that Google+ does not stand on its own. The "plus" is in the name after "Google". It's Google, plus. Google+ is just a frontend, an entry point. It's the Yahoo landing site for all of Google's services. Youtube, Google Search, Picasa, they are the "plus" in Google+.
Google+ is not and never will be (and never wanted to be) a Facebook. Google wants it to be a grouping of their services in a way that's easy to consume and share. I'll admit I didn't read the entire article, I skimmed it because there are about a billion points being made in the fashion of a one-man argument.
The entire article could have been just this one sentence:
And yes, Google+ is indeed a layer that goes throughout Google properties.
It is illogical for the author to be irritated by reality. Taking Google+ by itself and comparing it to Facebook is equally illogical.
