Google launched +1 Button to find exactly what you’re looking for when someone you know already found it. Users searching for a particular article on Google can now see what their friends have liked, making it easier for them to pick the best out of the lot. +1 is currently available on searches in Google.com when you are signed in.
In order to +1 things, you first need a public Google profile. When you create a profile, it's visible to anyone and connections with your email address can easily find it.
Your +1’s are stored in a new tab on your Google profile. 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.
