My client is asking for a Google+ share button alongside the Facebook, Twitter, etc. ones. I don't have a Google+ invitation yet, but it seems from screenshots that Google+ has the concept of sharing a page; however, I'm not getting very far with searches, which instead turn up information on the Google +1 button.
What's the situation? Is there a Google+ share button? Does it reuse the +1 button? Or the Google Buzz share button?
