Google +

So google recently opened this new social thing (whatever you wanna call it)
to every google user.
So does anyone have any strategy on how to take advantage of it yet ? Does anyone have experience with the new platform?
Please, share your experience, so the rest of us may not have to waste countless hours.

Are people really using it???? I don't know but here in Brazil most of the people just signed up and that's it, nothing more.

When I log into my profile I feel like Will Smith in "I am Legend"
