For now, Google+ sill feels very elitist. And in a bit more time, it will have just the perfect group. And then there will be a crowd but it is still the minority. And in theory, once it is crowded, I won't even care because of circles.
I am about to accept that this simply won't happen... Maybe we will have to wait a few more years before El Goog takes over the internet fully (assuming the internet is still there after congress is done with it).
