RDFaification of Drupal 6

You don't have to wait for Drupal 7 to RDFaificate your Drupal site. I spent yesterday tweaking my space, and if you access the site now with a tool, such as the Semantic Radar Firefox add-on, you'll see all sorts of semantic goodness. I used a combination of plug-ins and theme modifications to make my changes, and will probably add to the overall effect over time.
