Disclaimer: I'm a prototype / scriptaculous / lowpro junkie.

My big caution with all of these frameworks is the same as... well,
the caution you get whenever moving to a technology with a higher
level of abstraction: it doesn't totally save you from knowing about
the underlying tech. If you don't know how XmlHTTPRequest (or DOM
manipulation or events or javascript's peculiar object model)
*works*, then going beyond what the libraries give you for free is
gonna be hard.

That being said... if you try to write your own cross-browser event
code today, you are a fool ;-)

I *heartily* recommend source diving in these libraries. Seeing how
experts code js has been immensely helpful for me -- just as crawling
through ActiveRecord has been invaluable in learning ruby.
