We recently reported on a new feature Google unveiled for the +1 button: recommendations. When you hover over the button on a site, it will now recommend other content on that site based on +1's, providing a way for users to discover more well-liked content on the site, and possibly drive some additional pageviews for the publisher.
Here's what it looks like:
It's also nice that links open in new tabs, when clicked.
Google announced today that the feature is rolling out for everyone. Users in the Google+ Platform Preview received an email that said:

Early feedback on the feature has been positive, and it provides webmasters with another reason to seek more +1s from users.
