It's a shame they don't have a leader board on that site; I completed the challenge in 4:21, but I have no idea whether that's good, bad, or indifferent among everyone who's done so. A Twitter search on 'I completed "You Can't JavaScript Under Pressure"' suggests that score is merely on the good side of indifferent, but given the relatively competitive idea behind the whole endeavor, it seems like formally ranking completion times would be a useful thing to do.

(The "you won" screen is also godawful, not least because of the potential risk of triggering seizures in the epileptic, but also very much because it's incredibly ugly. I mean, I know that tasteless is the new tasteful, but really.)
