FYI, in addition to the links at the OJR Wiki, I’m keeping a running list of more diverse Hurricane Katrina links (in addition to the usual collection) at my OPML link blog. Some recent links:

• Missing person/survivor sites’ listed
  at Yahoo: Thanks to Elizabeth Osder, I now have this. If anyone knows of any other sites collecting such information — formally
  or informally — that aren’t on this list, please let me know.
• FCC is coordinating communications tech aid. Details at Boing-Boing.
• This list at the central federal Hurricane Katrina site
  illustrates the difficulty of matching people with the missing and of
  tracking the missing. There are about a dozen different sites
  collecting info mentioned here and I know there are many more where
  people are posting. For instance, the list doesn’t include Craigslist
  or many smaller blogs and sites.
• The remarkable Interdictor asks that anyone linking to his blog use
  http://mgno.com instead. The web cam feed from 650 Poydras is being
  mirrored at http://old.mises.org:88/NO2
