Resig in this presentation (warning: video autoplay), in response to the last question, said that while it's slick if you simply throw jquery into it you'll just get broken javascript out: http://developer.yahoo.com/yui/theater/video.php?v=resig-tes... I wonder what has changed?
(Maybe just not running it in advanced mode; at any rate, they're reporting a 13% decrease in file size: http://github.com/jquery/jquery/commit/3fd62eae9df3159fc238a...)

FWIW, I do use a $.bind method that I got from somewhere in my own jQuery code.
However, in the years since I made some of those technology decisions, jQuery has become the leader and thus more and more 3rd party technologies have been built around it.
I've recently switched to jQuery from mootools but I had to seek out a lot of plugins and other libraries (and build some stuff myself) to reach the same levels of capability but ultimately I'm happy with the results.
edit: and yes, 4x is a constant fraction, as opposed to an asymptotic improvement. :)
Great work - coding javascript is seriously easier than it was before JQuery came along.
