Does +1 affect my siteís performance in search?
Content recommended by friends and acquaintances is often more relevant than content from strangers. For example, a movie review from an expert is useful, but a movie review from a friend who shares your tastes can be even better. Because of this, +1ís from friends and contacts can be a useful signal to Google when determining the relevance of your page to a userís query. This is just one of many signals Google may use to determine a pageís relevance and ranking, and weíre constantly tweaking and improving our algorithm to improve overall search quality. For +1's, as with any new ranking signal, we'll be starting carefully and learning how those signals affect search quality.
Seems like a little more than a hint...
