This is what I was talking about when I said people going on about invites, nymwars and Google Apps were missing the forest for the trees. Google is taking this very, very seriously. They aren't afraid to leverage their previous success. Expect Google+ to be all up in search, maps, and a default app on Android.

Whether this is a good thing is an entirely separate issue. Personally I don't care for social networking, but Google has shown a unexpected amount of panache with this. I do think it is such a singular focus that it may prove a distraction (especially since I think social networking isn't a good fit for Google). The stuff I love from Google may suffer. But they are going broke.
