Share when it matters. +1 lets you share recommendations with friends, contacts and the rest of the web when your advice is most helpful – on Google search. Or, if you want to start a conversation right now, it’s easy to pick the circles who’ll find it interesting and post to Google+.
Each time you click +1, you're adding to the batch of cool, helpful, or just plain ridiculous things you've found across the web. You'll find your full list of +1's in a special tab on your public Google profile. You can show your +1's tab to the world or choose to hide it. Either way, it's the place you'll go to personally manage the ever-expanding record of things you love around the web.
