Google Plus has introduced Annonations in their +1 button, thereby making it more social.
When you visit a website and hover over the +1 button on that website, it will show you the list of some of your friends, who did +1 that particular website. This change was rolled out late last week and now, you can make these recommendations even more visible to your users. Simply update the +1 button code, and an inline annotation will show next to the button.
Google has also unveiled new code for the +1 button that will display the faces and names of friends that have used the +1 button. This feature works much like how the Facebook Like button appears
Everybody can see aggregate annotations. Signed-in users also see personalized annotations from:
- People in your Google+ circles
- People who have you in a circle in Google+.
- People in your Gmail (or Google Talk) chat list.
- People in your My Contacts group in Google Contacts.
- People you’re following in Google Reader and Google Buzz.
The code for the standard 24px button is as follows
