(I'm the author). Your last point is very true, and the chart tries to make it very clear it's only talking about public posts. Obviously entirely true that they could be using it purely privately, but I still think is an observation worth making that they're not using it publicly.

As far the correlation in general, as I mention in the thread above, these aren't normal people, they're the leaders/overseers of the company using (or not) a landmark initiative whose leader (Vic Gundotra) clearly thinks that ideally it'd be used for both private and public interactions. At the very least, it'd look a lot better if they had accounts, tried making a public post (even just to congratulate the team publicly), and looked a bit more publicly engaged.

[hosh]

@degusta Whether these leaders publicly eat their own dogfood or not is a matter of rhetorics and strategy. If that were your thesis and narrative, we would be having a much more interesting conversation.

However, you didn't entitle your article, "Google Management Doesn't Care About Google+" You said, "Google Management Doesn't Use Google+". The former expresses your perception of Google strategy backed by the data you've collected. The latter is merely link bait.

I do congratulate you. The link bait worked.

Actually, I agree that might have been a better title - would have avoided some of the controversy while making the same point. (And, fwiw, I don't have any ads or make any money off my blog, nor did I really think the post would catch on to this extent.)
