Forrester Research just released a report discussing the open source CMS software market and identifying two that they should pay attention to: Alfresco and Drupal. Drupal is getting a tremendous amount of love these days and it's not surprising.

The formation of Acquia (think what RedHat is to Linux, Acquia is to Drupal) has given a tremendous amount of credibility and a promise of direction within the platform. Companies like Acquia put a little fear in the open source community that control is being taken away from the community but Acquia has taken the right approach and been smart about its place in the community.
