Looks like not even mighty Google itself is able to resist the charms of a bit of widespread internet shorthand. +1, whether used to uprank an Engadget comment or in freehand writing to signify one's support / approval of something, is making its way into Google search results. You'll soon be able to throw a single thumb up on links or ads you find useful, which will then be used to inform your buddies about the value of that site. Recommendations are filtered using a typically complex algorithm intended to make them as relevant as possible, with people within your social circle (i.e. Gtalk buddies and Gmail contacts) getting a higher priority. The new +1 button will start off with English Google search and ads soon, to be followed by more products in Google's portfolio and potentially more social linkups, such as via Twitter. The usual explanatory video follows after the break.
