We use Drupal for a lot of stuff in our group at PSU. From our Liquid ANGEL project to Podcasts at Penn State, Drupal is being put through the paces all the time. I have friends who have gone to Drupal for their blogging platform and more and more people I know are getting into the act. We used Drupal a couple of years ago when we did blogging for the Governor's School, the blogs@si project, and IST2U.
That's a long intro paragraph just to point to the fact that Drupal is getting a whole new installation process with some nice features -- the coolest one the ability to easily create custom distributions. At any rate, Drupal is getting better (and easier).
