We're pretty hot into this stuff at MPR with our Public Insight Journalism project that has attempted this sort of thing several times. I'd say the jury is still out on the technique. But it's worth looking. I've written extensively about the great polarization in political discourse. But I don't see the voting public as being completely unwilling participants in the situation; forced into the behavior that I won't bother documenting here. How to turn the course of discourse? Good question.
