Google recently released two updates on their Plus platform to the users on platform preview.
These changes are now being rolled out to all users.
Clicking the Google +1 button would automatically load the page elements saving a click if you want to share it.
And the Google Plus Badge now has a follow button to quickly circle the related page.
Google said in a post on the Google Plus Developers Group:
Our most recent previews are graduating to public today. The updated +1 button sharing flow as well as the Follow button on the Google+ badge will roll out to all users.
