I originally wrote this article for the Xaneon Development site way back in August 2005. After Xaneon shut down and this article became unavailable, a number of people e-mailed me to ask for it, so I dug up my local copy and decided to publish it here. Note that since this was written, Mambo has become Joomla and both Drupal and Joomla have evolved and come out with new releases. Nevertheless, for what it’s worth, here follows the article in its original form.

Since our announcement regarding the impending demise of XE2, we’ve received a ton of e-mail from people asking us to elaborate on the reasons we decided to “defect” from Mambo to Drupal. Instead of answering this question over and over, we’ve decided to publish a brief (well, that was the intention, anyway…) overview of what has led us to, ultimately, abandon Mambo.
