Google rolling out a new experiment to show a Share link in Google search results in place of the +1 button, making it easier for you to share a website with your friends. Now when you click the Share link next to a result, you can add a comment about why you found it useful. You can then choose if you want to share it publicly or just to your Circles and it will post to your Google+ stream, making it easier for you to share directly from the search results page.
