The National Aeronautics and Space Administration (NASA) is using Drupal for their Academy of Program / Project and Engineering Leadership website (APPEL). Sweet!
The Flemish Radio- and Television Network (VRT) uses Drupal for 16+, a community website to accompany one of the television programs they broadcast. The website allows people to upload and share pictures, music and video. Belgian newspaper De Standaard described 16+ as the "Flemish YouTube". Belgian newspaper De Morgen refers to it as being an "online community".
Development of the website was coordinated by the Interdisciplinary institute for BroadBand Technology (IBBT), a research institute founded by the Flemish government. Next week I'll meet some of the people behind 16+ and IBBT as I committed to giving them a short Drupal presentation.
Hagen Graf has written a German Drupal book: Drupal: Community-Websites entwickeln und verwalten mit dem Open Source-CMS published by Addison-Wesley. I got a copy of the book in the mail today and took some pictures. Thanks Hagen, Boris and Uwe!
