The thing I notice about Google+ is that the only thing people use it for is talking about Google+.

This strikes me as a bad thing. Didn't Orkut and Wave and other 'failed' similar services from other companies have the same problem? Limited appeal? Too recursively tied up in their own cleverness?

The thing people hate about Facebook is the trivial uses the muggles put it to. But there are not 500 million techos in the world.

Unless and until people start talking about mundane non-techo stuff, I won't consider Google+ to have succeeded.
