The cross browser DomReady event is a great feature in all the good JavaScript libs. Basically you use it where you'd normally use the window onLoad event, the only difference is that it doesn't wait for images and other large assets to load before firing. So when people are in a hurry or the page is just slow they don't get a lessened experience because your progressive enhancements haven't done their enhancing.
