Huge CSS files can gunk up your page loads, creating annoying wait times for your readers and (if things get really bad) even driving people away before the page fully loads.

Today, we bring you an informative video from the recent 2010 O'Reilly Velocity conference on how to optimize CSS while avoiding some of the most common mistakes developers make. It's especially useful for those of you with big CSS payloads. The first speaker is a little dry, but the fun picks up when Nicole Sullivan takes over about five minutes in.
