Google has just unveiled an all new Google+ share button that will hopefully help visitors to your site go beyond a simple "+1" of your content.
Via the Google+ Developers blog:
When your visitors come across something interesting on your site, sometimes you want to encourage a simple endorsement (like +1). Other times, however, you want to help visitors share with their friends, right away. Today’s new Google+ Share button lets you do just that.
When someone clicks on the g+ share button, they'll see the share box, which allows them to add a comment as well as choose which circles they share with.
And just like the new "g+1" button that Google launched for sites back in March, the g+ share button will turn red once you've shared the content.
Google's g+1 button has allowed users to share content to their Google+ stream for awhile. Once you click the button, hovering over it will call up a share box that also allows you to add a comment and pick your sharing circles. It automatically defaults to public sharing, however, which the new g+ share button does not.
But an actual g+ share button should make it more intuitive for people to share content across the platform. That's considering there's a decent amount of people out there that have the impetus to share content on Google+. Site owners: the button is officially live and you can snatch the code over at Google Developers.
