Greg, Excellent points.

One possible solution to the "fog" problem on internet forums is to require participants spend some time researching the topic before posting. Years ago as a high school debater we were required to follow rules, present logic and quote published evidence to make our points. There were no shortcuts to avoid research and thinking. People should be encouraged to not abuse their right to free speech.

That's partly why this particular radio show is successful. People are naturally encouraged to present themselves properly. They also have a thoughtful and considerate moderator who never tries to push his own opinions. Everyone listens to this show.

Maybe Omidyar.net needs to set up a national TV or radio station dedicated to giving people a place to voice their opinions. We could organize debates and tie-in the web-based discussions with live radio/TV discussion, much like CNN does.
