We once lived in a world of organically evolved human scale villages and cities. Since World War II especially in North America, we have seen the spread of suburban and exurban sprawl and a wave of auto friendly, unwalkable and not human scale architecture. The members of the Congress for the New Urbanism, whose site is on a Bryght VPS, are part of a worldwide movement (of which Vancouver, home of Bryght's headquarters, is a leader) to restore the livable, walkable community balance that we've lost.
CNU has taken advantage of Drupal's unique ability to provide a beautiful site that is a brochure site as well as dynamic online community site (check out their blog, forum and Salons) as well as a members only site and more.
CNU also have a companion Drupal site for their upcoming New Urbanism conference, CNU XV (CNUXV.org)
Call me a dreamer but I see Drupal as ideal platform for building the online version of new urbanism. Imagine a whole slew of great online communities fostering online discussion and learning in order to help 'renew the web' from a static brochure web to a conversational two way web powered by Drupal sites (and of course other technology since Drupal is totally open everybody can participate) exchanging data using RSS feeds, XML-RPC, publish and subscribe, and other open data standards.
