We’ve been using Drupal for two years now, and it has become the main CMS for our development work. Which is why it is interesting to read this article http://www.xconomy.com/2007/12/20/a-big-drop-in-the-bucket-for-drupal/  Basically, the company Acquia aims to be to Drupal what Redhat is to Linux, which to me is a professionalization of the Drupal product. I think this is a pretty great idea. Drupal is great, but lacks such fundamentals as a well written user manual, or more careful upgrade instructions. Plus, some modules are not quite complete, so maybe this will be a way for some of them to be addressed as well.
