My First Three Point of Inquiry Shows--Requesting Feedback

I just started a comments thread over at the Point of Inquiry forums to ask what folks think of my first three programs--on vaccine denial with Paul Offit, on climate denial with Michael Mann, and then on science journalism and disaster with Andrew Revkin. We've determined that I'll be taking next week off, and a D.J. Grothe show that was in the can will air instead. So now is a great time to evaluate strengths and weaknesses and plot new directions. This is, after all, a new experiment, and I want to learn from it and progress. So any thoughts are appreciated. Leave them at the forum thread, or leave them here--and thanks!
