This site uses a "self-referential" educational strategy to expose Drupal concepts to developers

This site uses an overtly "self-referential" educational strategy to expose Drupal concepts to developers, rather than being based on contrived examples. For example, a contributed module menu link in a block might be called "A contributed module menu link in a block" and would appear in a block. The demonstration panels page is simply called Demo: Panels page, it does not pretend to be a panels page for a fictional online lolly shop.
