Business Computing Magazine in its July 2008 edition selected Alfresco Community Edition 2.2 as the Editor’s Choice Award winner noting

that Alfresco was a “top notch open source CMS package” with “Web 2.0 functionality.” Alfresco was also recognized for its ease in publishing new articles on the fly as well its ability to add mashups, site maps, RSS news feeds and other items to aid in the appearance of the Web site.

On the other hand, Forrester Research noted that Alfresco and Drupal earned its distinction as the two top CMS out today because:

• Both have taken pages from the commercial vendors’ playbooks [i.e., enterprise-class support, stability, etc.]….
• Technologists praise the product architectures….
• Both have strong professional communities.

Btw, Alfresco Community Edition is now known as Alfresco Labs "to more accurately describe the ‘laboratory’-like process offering the latest functionality, a daily build, and the platform for the Alfresco Community."
