Drigg allows you to promote stories automatically based on your users' votes. Unlike other Drupal and non-drupal solutions, you can do this with amazing simplicity.

Drigg can be installed in two ways.

The first one is the "express way" - a "Drupal distribution" offered at drigg-code.org which includes a working copy of Drupal and a basic database schema that will give you a pre-configured site.

Or, you can do it yourself. Doing it yourself is not actually much more complicated. You will still need to configure your web server properly. You may still have to refer to Drupal's official documentation if you have any installation problems.
