Google Plus : +1 Button for Google Chrome

Google Plus - Google Chrome +1 Button Extension:
Google has released its  official +1 button extension for Google Chrome. With Google +1 button you can rate and bookmark a web page, anywhere you go on the web. The +1 button is a shorthand for "this is pretty cool" or "you should check this out." Click +1 to publicly give something your stamp of approval.

You can manage your +1’s in a new tab on your Google Plus profile (https://profiles.google.com). You can show your +1’s tab to the world, or keep it private and just use it to personally manage the ever-expanding record of things you love around the web.
