Funnily enough Google was really onto something with the concept of Circles. We do not, and should not, want to share everything with everyone a la Twitter and Facebook. The execution of G+ was bungled disastrously, and ass-backwards policies like Real Names ran directly contrary to the original notion of having multiple identities/profiles to present to different people. But I do wish someone would run with this idea again. ... But maybe we don't need to. Social networks with segmented audiences/identities have existed since forever, they're called BBSes and Forums.
