Google today did something smart in social - they offered a human way to do something they had already offered - the ability to indicate your approval of a search result. Previously, you could push a result up or down, but that action was not social in nature. Now you can '+1' a search result, so as to indicate the result was good and/or valuable to you. That recommendation is then translated to others in your social graph."
