It's probably worth revisiting this. Where is everyone with +1?
I saw a brief surge in usage of it after it got a lot of media attention but now it's barely getting used again.
Every now and then a bunch of Facebook users screams about how much they hate Facebook and tries to get everyone to follow them to Google +, but it never really happens.
I still have the Google + button my site... but does anyone really think this is ever going to take off?
