The folks over at PostWorthy have recently created an online tool for analyzing user relationships at Digg called Digg Stalker . I have recently re-discovered Digg after abandoning it for reddit by means of their ever improving profile tools. The ability to add friends and track their submissions adds a whole new dimension to social networking that is currently lacking in sites like reddit. Digg Stalker provides a convenient platform for analyzing these relationships without having to be constrained by the digg interface.

Look at the bottom of this article and you will see a "Digg This" button using the familiar digg icon. Adding this button is an easy way to increase the visibility of your blog. To add this digg button simply install the Digg This module from the Drupal website. It's installation is surprisingly simple (as are most Drupal modules).
