Drupal, which is one of the most powerful & free content management system has a new module named Drigg for creating Digg-like websites.
Unlike other Drupal-based solutions, Drigg only needs:
- VotingAPI — a powerful Voting API available for Drupal.
- A voting form based on the VotingAPI. The forms of choice are provided by Extra Voting Forms.
- The User Karma module.
