The "Hacker News Circle" Google+ re-shares an updated circle every 5 minutes. Clicking "Add Circle" allows you to copy that circle into one of your own.
I just made a straight copy called "Hacker News" in my circles where I dump the shared circle.
All this is implementing a feature that Google+ desperately needs: a public circle that users can subscribe to rather than copy into their private circles, like Twitter's lists.
(Note: I am not the creator of the Hacker News Circle, just a user)
