I recently discovered a very good weblog focusing on current events in New Orleans. Anyone interested should head over to Metroblogging New Orleans.
On a related note, Network World recently published an article on communcations network disruptions in the wake of Katrina, and what businesses are doing now to mitigate risk from a future storm. It's a very interesting article, and well worth taking a few minutes to read.
