Button Features:
+1 button is shorthand for "this is pretty cool" or "you should check this out." Now you can +1 the pages you think are worth visiting no matter where you are on the web. +1's can help your friends, contacts, and others on the web find the best stuff when they search. By installing the +1 extension, you can publicly +1 any page that you're visiting with one easy click. You can manage your +1’s in a new tab on your Google 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. Please read our Google +1 Button Privacy Policy (http://www.google.com/intl/en/privacy/plusone/) for basic information about +1 button functionality./blockquote>
Also this is just phase one of the +1 button as stated in the google+ post by Timothy. “It doesn’t yet have the ability to share to Google+, but we’ll automatically update it over time after you install it. So be on the lookout for new +1-tastic features in the future”
I’ve installed it and will be +1 various sites now easier using the Google Chrome extension. Note it also rumored that Google may be changing their search algorithm based off the usage of the +1 button.
