I've still not looked at JQuery- I use
Mootools, which by all accounts does just the same stuff.
I'm yet to find a decent resource that compares all of them so I can make an objective choice... as it is, I know how to program Mootools, so I'll stick with it. Prototype is (or was, when I tried it) far, far too big.
