Well, don't provide a test like "you'll be in the hospital by #20" if you haven't vetted the results of it first.
My personal advocacy for the Closure Tools does not discredit my views on other tools, and I'm hoping this ad hominem nonsense doesn't fly in such a forum. Quite a few people come into the IRC channel and are using the Closure Compiler with jQuery and I don't give them shit. I take no issue with you using, liking, preferring jQuery.
You know why I like Closure? Because it makes the hard things possible. When you're talking about JavaScript running the web, it's websites like Gmail that matter the most. And you'd have a hell of a time getting Gmail to run as smoothy as it does using a library like jQuery, or even ExtJS.
