The DiggThis module for the Drupal Content Management System provides a Digg button for users to add to their nodes. This button will provide a Submit link for visitors to submit this story to Digg, or if it has benn previously submitted will show the number of Diggs it has received. You can add the button per content type, set the weight to have it show up where you want, select the size of the button, and change background color of the button. This module is very helpful for Drupal users that are using Digg as part of an external Search Engine Marketing effort.
