It's a button to share a hub on Google+. Google+ is a social networking thing like Twitter, facebook etc. If you +1 something it's basically the equivalent of a facebook like. Google likes pages that have a lot of genuine +1's but you should avoid "liking" only your own hubs etc. as that can be "spammy".
