I'm not going to pretend this is comprehensive !
The panelists include John M. Barry who wrote a book about the 1927 Mississippi flood, among other things. More at http://www.JohnMBarry.com
Karen Gadbois is a blogger who started with all this after Katrina, and didn't know what a blog was before that.
Her site is http://www.squanderedheritage.com/ and documents how The Powers are trying to tear down homes and other buildings that are just fine, thank you very much, in order to clear space for highrise developments and such.
http://www.City-works.org is all about what's going on with local organizations that are trying to revitalize NOLA. The rep on the panel is the Rev. Marshall Truehill, Jr.
Al Giordano is a blogger/investigative journalist with NarcoNews.
http://narcosphere.narconews.com/... He and NarcoNews come with a fantastic amount of credibility, background and knowledge about all sorts of things and is one of the real blessings of the blogosphere.
Here's a reference site for those of your who might be in the neighborhood of a levee in some other part of the country that needs watching: http://levees.org/
