Review my app, UnusedCSS.com
benologist: It's cute but I think the ramifications for left over CSS are pretty insignificant except in some very rare edge cases.It would be cooler if you could feed it a CSS file and have it return a better version of it, well and concisely formatted without redundant declarations, using shorthand etc.That would take this from something that doesn't really need doing - like css minification in a world where gzip exists, such as our world - to something that would show people a better way to produce CSS and still retain that original functionality if you're convinced there's a need for that.
