Even better for competition, Google+ actually emphasized better privacy as a competitive differentiator, forcing a comparison and response from Facebook. So even if you think Facebook is better than Google+, here's a consideration: Joining Google+ will actually make Facebook better for you. If you show you have somewhere to go, they will try harder to make you stay. If the primary differentiator is privacy, or you make your move in response to privacy changes, you can push the entire market in the right direction (you and a few other millions).

At last, privacy is improving not because we demanded better privacy but because we can put our clicks where our mouth is: shift our daily attention to another service and watch the market respond.
