I would like to commend to you Salon's Katrina coverage. Among the highlights.
1. Sid Blumenthal's roundup of Federal level mistakes, and the bad ideology that drove them.
2. The first attempt I've seen to get a grip on the exact number of the dead. It is in the tens of thousands, not the thousands.
3. A great video highlight reel of the news coverage, including reporter freak outs.
