I've been working on an early stage startup which does something very similar to this, although less celebrity focused and more on common circles. It's funny actually, when Google+ happened, I figured they did exactly what we've been working on, but they didn't. Seeing as everyone on HN seems to want something like this now though, it seems to be putting a lot of pressure on.
