Google+ Communities Indexed in Google Search

Not only can individual posts in public Google+ Communities be indexed by Google search, but the Communities and even categories inside Communities can be indexed as well.

The result below was #3 (after news results) for an incognito search for "vine videos community". It links to the Discussion category of my "Vine Videos - A 6 Second Video Community" here on G+. If I search for "vine videos discussion," it comes up #1.
