How do they serve different purposes? It's just a grouping of friends that is common among many people.

  The big difference is that my friends join a group, whereas I add my friends to a circle. They don't need to do anything; they don't even know they're in the circle. The purpose is for me to control who I share things with. With circles, I don't have to worry about someone joining the group that I don't want there or hurting feelings by having to reject requests to join. At the same time, I'd still like to be able to mutually join groups as well, and it's easy to imagine scenarios where I would add a group to a circle (or where they'd be coincident). The two concepts are complimentary.

    Yes, sorry i misread you. I assume it's going to be exactly like a group, it would just be embarrassing to call them "groups". maybe "shared circles" or "clubs".
