Google’s Management Doesn’t Use Google+
This thought: <i>Further, I think it’s reasonable to assume a correlation between private use & public use</i> kills the whole article. No, it isn't a reasonable assumption. If you look at my Facebook without being a friend of mine, you get a picture of me. Five years of use and that is the only public thing I have published. And I am just another dude no one cares about. I am sure billionaire CEOs and board members who have actual reporters, normal everyday gossiphounds and even crazies caring about their personal lives have even more incentive to be private. Google+'s promise isn't that is a combination of Facebook and Twitter, it is a social network where it does what you want it to. And if Google management wants their sharing to be private, that is good. I suspect a large number of their users have a similar outlook.
