I have, along with tens, perhaps even dozens, of others been concerned that Google's top brass seems not to have been posting on Google+.
After I and others had expressed doting concern that Google CEO Larry Page hadn't posted anything publicly since August 16, Business Insider decided to out the anti-social networkers among Google's above-the-cloud echelons.
Its work has already born fruit. Or, more accurately, a dragon. Well, not really a dragon, although that's how Google's co-founder, Sergey Brin playfully describes it.
Brin hadn't posted since August 29. But today he offered "the dragon" and two other pictures, with this message: "You may think I captured this image of a 'dragon' in a far off land but in fact it was very close to home. Let me know where you think this is and as always I appreciate feedback on the photo. I'll update the post later today with the story."

For my own part, I am guessing that Brin bought a vast complex in Los Gatos, Calif., and inserted a zoo in its midst.
This doesn't appear to be a guess the 414 commenters on the post have thus far offered. Some have suggested the San Diego Zoo. Others, well, the San Francisco Zoo.
Google today opened Google+ to every living human. Although it is questionable just how loud its fanfare will have to be to interest every living human--especially with no obvious promotion, or indeed, obvious point of difference. (Other than the less than entirely winning: "It's a bit more complicated, but it's fun!")
Perhaps Brin's gesture is a nod to the notion that Facebook will allegedly announce a major redesign of its site this week.
Can we expect that Page will find the time to post something on Google+ before Facebook reveals its wares? Some intimate footage of the Mayweather/Ortiz fight, perhaps.
