I personally think the "circles" concept is going to be the killer feature, at least for me and my wife. Being able to easily post things that not everybody on your list will be able to see is something I wish Facebook had, especially for those of us unable to resist the guilt-pressure to accept family members into our friend list...

This is the thing Facebook got never right when they opened from college to everyone. It was obvious for so long and they never did anything about it, i mean the word "friend" alone is limiting the whole concept.
