So, um Drupal owes a lot to Scoop (http://en.wikipedia.org/wiki/Scoop_(software)) and SLASH (). IIRC, Scoop was built off slashcode, and Drupal off Scoop. FYI, the most famous site using Scoop is probably DKos (http://www.dailykos.com/).

The three systems do share a need for a real programmer to customize and maintain.
