Knock knock! Who's here?

I'm really curious what has happened to the Daily Kos readership over the course of primary season. It's pretty clear that we tipped over to Obama's side pretty heavily, and then there was the "strike". So I was just wondering who's still here -- is it all Obama all the time? Are there Hillary lurkers? How many people are sick of primary season -- and of those, who's still here posting on non-primary topics and who has left?

Legal scholar Cass Sunstein had an argument about how the internet is harmful to open debate because it fractures us into multiple non-interacting camps that make people's opinions more extreme. I don't necessarily agree with the claims he makes, but I wonder whether the dynamics of Daily Kos over the past few months support his point of view?
