The Google Pluspocalypse

It's been clear for a while that Google is hell-bent on making Google+ work, and its motives are both reasonable and clear — from a business perspective. But at times I find myself wondering if Google has, like, actually lost control of its social network; if a lumbering green robot is stalking the campus, crashing through doors and zapping product managers at random with his +1 death ray. It would explain a lot. Anyway, uh, Gmail has Google Hangouts now.
