A little off-topic: but does anyone who has tried Google Circles know if they're as easy (I've read many times that they are more fun :)) to make as Facebook friend lists? To make a list in Facebook I add two or three people to it and Facebook guesses pretty damn well who else I want on that list (presumably by doing something like approximate clique cover on my component of the social graph). Maybe other people's social circles bleed into each other more and that might confuse Facebook algorithm, but for me it worked like a charm.
