Kudos for MT
If you take a look at http://atlas.atlcon.net, you'll see the new site. Very little of the site is maintained outside of Movable Type; the vast majority of the pages are generated automatically as I add new content in Movable Type. For example, the most recent news items automatically populate the main page. Category Indexes (accessible by clicking on a category header in the right side toolbar) are automatically refreshed every time I add an entry.
What I especially like about this is that I can have a very dynamic site but still keep it in HTML formatting, which means that the search engines can easily crawl the site and index it. I'll have a better chance of being ranked high this way. Top notch tool. Check it out.
