We're excited that the folks over at The Acquity Group stepped up to produce a great one-hour presentation for JoomlaChicago tomorrow. They'll be doing an unvarnished comparison and contrast of four of the top Open Source Web CMS solutions for enterprise:

 - Joomla!
 - Drupal
 - Alfresco
 - Magnolia

Last year, we compared Joomla! and Drupal. The goal at the end of the day is to see which WCM is best suited for certain situations. We'll be posting the report online. Stay tuned!
