I have been experimenting trying to integrate this site (powered by Drupal) with Facebook and Twitter. The Idea is to let my friends comment here using their accounts on those (and other) platforms.

So far I have not had much luck, because the FB module for Drupal cannot handle FB usernames, so if you commented here, your comment would appear as xxxx@facebook.com; the Twitter module, is still buggy and it seems that development has halted lately (hopefully I am wrong).
