I’ve been a little obsessed with improving the speed of web pages via minified javascript and css files. YUI’s team not only agrees with this, they recommend gzipping your minified js and css files. For a while I’ve been calling YUI Compressor inside my push to production scripts to do the deed. However, with this new mention of gzipping, I think might be exploring other options such as the method mentioned on the page which originally linked me to that awesome YUI writeup; minifying and gzipping javascript and css on the fly using php.
