Using Dust-Me Selectors Plugin to find unused CSS selectors

Klaus Komenda as a good write up about using the Dust-Me Selectors Plugin. This is a Firefox plugin that scours your CSS files to find unused selectors so that you can shave some more bytes off the file size (as well as help maintainability). Version 2.0 of the plugin, written by SitePoint, now has a spider to do the crawling for you so combined with a sitemap.xml file this should be relatively tedium-free.
