1. Big Brother loves you

2. Google's competing social network to Facebook.

It's a bit more professional and presents less security/data-mining concerns. It's a different approach to the social-net thing.

3. Google is just a shadow organization for the NSA.

And they want to get to know you a little better! See, nothing to be worried about. Facebook = CIA.
