Cool site. One thing though: please note that a Creative Commons button is meaningless when it doesn't link to a specific license (BY, BY-SA, BY-NC-SA...). Any of them would conflict with "all rights reserved" in the footer, too.
I know you are not looking to add new districts, so this proposal is intentionally not serious! Troy (or Babylon): sites that used to be actively updated but haven't received an update in over three years. Potemkin Village: sites that have a good-looking index page, but links to all other pages are broken. Germania: sites that started with megalomaniac plans but never materialized.
