Connectivity to your social circles is something Facebook provides that nobody else provides. There are other ways of connecting social circles, but due to network effects, they're all worse.

There's no site on the planet other than Facebook that lets me interact with my entire family all at once in a way that I know will reach them.

I'm not a facebook user but I did set up a google+ account while it was around and i did like that circles paradigm they had. For whatever else was wrong with that thing to make it crash and burn so hard and so quickly (other than google's corporate adhd and constantly being in 3rd or 4th place).. I did like that concept of circles as ways to target your content.
