A colleague just sent me a message about a new WorldBank site that was developed using Drupal.  It's very impressive.  The URL for the site is http://data.worldbank.org/

The site was created by a company called DevelopmentSeed.  These are the same folks that created the FeedApi and Feeds modules.

I'm going to poke around a bit on the site but it looks like it might be worth showing the potential of Drupal using this site at the AgriDrupal workshop.
