It also had ridiculous rules to enforce "quality" but in the end it was to enforce user work by convention. Like one question per question only. Nobody could just post a project with a set of questions. Nobody was allowed "stupid" questions, nobody was allowed to do in depth meta excursions, the site reeked of rigor, where a true academic would have allowed for rigor to go lax when moving away from certainty aka to the funnel stage of enlightenment. It also would not allow for grouping questions into a format thats similar to the youtube "project" format.
