The +1 button is shorthand for "this is pretty cool" or "you should check this out."
Your +1's can help friends, contacts, and others on the web find the best stuff when they search.
Sometimes it’s easier to find exactly what you’re looking for when someone you know already found it. Get recommendations for the things that interest you, right when you want them, in your search results.
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.
