Here are some thoughts from each of the discussion leaders so participants can get a head start. Take a look and join in the conversations even if you can't be there in person. Remember, this is an unconference where the words "audience" and "panel" aren't in the plan; everyone who attends a session in person or remotely through IRC has the chance for an equal say. For more on the "unconference" concept see Dave Winer's pre-BloggerCon III explanation.
Most of the discussion leaders are hosting "Food For Thought" dinners Saturday night; more info here.
The dinners are another nifty Dave Winer creation The dinners are part of Dave's BloggerCon formula -- the Palo Alto journalism dinner hosted by Jay Rosen was where I met Robert Cox, one of the organizers of BlogNashville, and a number of other people who will be in Nashville. In fact, I think it also was where some the seeds for this mid-American conference were planted.
