As widely reported, whitehouse.gov is now running on Drupal. There's an interesting article and video (15 minutes) of discussion with the White House team about their use of Drupal. In response to a question, they replied that most of the site is out-of-the-box Drupal. The major customizations were in the areas of scalability and security. Yes, you, too can have your own version of whitehouse.gov. (Shameless plug: my new Drupal book is all about out-of-the-box Drupal.)
