Similar to the StumbleThis module that we had created earlier we have created another bookmarking module for Drupal - SlashdotIt module. Unlike the other social bookmarking sites Slashdot is very selective in terms of the articles that get approved from the submission queue also known as the Slashdot firehose. Use this module on your site only if you are sure that you have slashdot worthy content.
Check out http://www.slashdot.org and figure out the kind of articles that get posted at slashdot. If your site has comparable content then go ahead and use this module. The administrative options are similar to the StumbleThis Drupal module that we had created earlier. The module has been tested with Drupal 5.3. Please use the comments form below if you have any questions or suggestions.
