jQuery is an awesome javascript framework. I've been using for a couple years now and it has saved tons of development time and added some cool things to various sites.
One example is this site [url="http://www.citrusmedia.com/projects/torontohotels/"]http://www.citrusmedia.com/projects/torontohotels/[/url] (this is an early version, very unfinished. the site moved to another server to finish development, but that server is down). The form on the left there is a little overboard, but it works pretty well. Custom dropdowns, date selection via calendar. Play around, add rooms, change the number of children in each room, this would've been a nightmare without jQuery.
Anyways, point is, I really dig jQuery and I think you should check it out. Very easy to use, tons of tutorials, plugins, etc for it.
