In the Google+ Developers preview group, it was announced today that the Google+ badge is getting a couple of really good tweaks.
First, the “Add to Circles” button is going to become a follow button and when clicked, it will automatically add the account to your “following” circle. At that point, you can change circles or select a different circle, but it’s an easy one-click way to add a Google+ page to your circles.
Secondly, the sharing functionality is going to get a little easier. Currently, when you +1 something, you have to click twice to get the sharing dialogue to appear. This will now be the default functionality, which will make it much easier to share content on Google Plus. If you are a member of the Google developers preview group, you can already see this functionality in action.
