I think Facebook has had groups for a while - they just aren't exposed that well in the UI. (I don't think I've ever tried to use them, though, so maybe they're different from Circles in some way.)

Yeah but the key difference is G+ is pushing Circles upfront and hard from the get go. They are also implemented far better than anything Facebook has done along these lines. To truly get the benefit of Circles, not only do I need to be able to take advantage them but all my friends need to be using them too. If everyone is on board and using Circles effectively, the amount of noise overall goes down, and signal can go way up.

  Circles are awesome. The implementation is fun and animated. I think it would be awesome if you could share them as well. Make them grow as groups.

  .. oh yeah and of course. What about, intersection? Friends intersected with Work.
