I just read this from
Google +1 Button that having +1 on your website from friends or and acquaintances helps increase your site performance on search engines, with this I installed Google +1 snippets in one of our website for testing hoping to drag our rankings to the next level.
Perhaps we could help each other by giving +1 to our website, blogs etc..
Anyone cares?

The +1 button and search results
How does +1 affect search results?
+1 helps people discover relevant content—a website, a Google search result, or an ad—from the people they already know and trust. The +1 button appears on Google search, on websites, and on ads. For example, you might see a +1 button for a Google search result, Google ad, or next to an article you're reading on your favorite news site.
Adding the +1 button to pages on your own site lets users recommend your content, knowing that their friends and contacts will see their recommendation when it’s most relevant—in the context of Google search results. In addition, a user's +1's appear on the +1 tab of their Google Profile. While +1’s are always public, users can choose to make the +1 tab visible or invisible on their profile.
When a signed-in Google user is searching, your Google search result snippet may be annotated with the names of the user's connections who've +1'd your page. If none of a user's connections has +1'd your page, your snippet may display the aggregate number of +1's your page has received.
Does +1 affect my site's 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, +1's from friends and contacts can be a useful signal to Google when determining the relevance of your page to a user’s query. This is just one of many signals Google may use to determine a page’s relevance and ranking, and we’re constantly tweaking and improving our algorithm to improve overall search quality. For +1's, as with any new ranking signal, we are starting carefully and learning how those signals affect search quality.
Does +1 affect how Google crawls my site?
When you add the +1 button to a page, Google assumes that you want that page to be publicly available and visible in Google Search results. As a result, we may fetch and show that page even if it is disallowed in
robots.txt.
