Good news everyone: 1000 great Drupal powered sites are listed at DrupalSites.net! A big thank you and congratulations everyone! Keep it coming!
I don't visit the site too often, but have used it when I'm in a pinch to show someone examples of Drupal powered sites.
Ironically, I saw news of this event on Amy Stephen's blog whose strongest ties are with the Joomla! community. I believe this is the second time I've also mentioned her name in a Drupal post. Perhaps, a CMS as great as Drupal is finally winning her over?
