How so? I've heard good news about jQuery, but why do people like it
better (besides footprint)?

Maybe that's just lines. The main thing I don't like about JQuery is
ThatMany.linesOfCode(endup).lookingLikeA(TrainWreck);

I that's partly due to the train-wrecked-ness of the library.
Prototype isn't overly verbose - most calls to that (or
scriptaculous) are one liners in my experience. Sure there's times
when you want to chain things or queue events...

Well, there's that, and Prototype usage isn't much like vanilla DOM
scripting.

Examples? I'm interested in learning more.
