This reorganization of links project seems to be slowly morphing into the community site project. Drupal has actual documentation, almost all the features I want right out of the box, a sane database structure and a module API with the best features of ExpressionEngine's (it makes sense immediately) and PHP-Nuke (straightforward install).
I actually had PHP-Nuke in mind for a while, but Drupal has bumped it. Harshly.
