I was looking at it before you posted. I agree it is much better than static HTML.
I used to have static websites, and if I wanted to change any design element (excluding what could be done with CSS) I would have to edit every page. I called it changingasinglelinkin50statichtmlpagesophobia. My current site has a home brewed CMS, while certainly not as advanced as something like Mambo or Joomla! it still gets the job done.
I've tried to deploy mambo on a site, and because there wasn't much content to put up, and it wasn't going to be updated too often there was more functionality than I knew what to do with. New site's looking good :).
