So you think they should inject a third-party dependency instead of just some inline js? And that would make it more elegant?
The whole document.write block 27-51 (possibly the CSS-block too, but I'm not sure about this) could be written far more elegant in jQuery.
But the real saving is that "drag and drop" code - jQuery would abstract all that isIE/isNS crap from them.
...unless you're still being sarcastic?
