Learning Javascript and AJAX

I have dived (doven?) head first into some web technologies I have shied away from for awhile. I stayed away from javascript and AJAX for along time. Like everything else I have ever wimped out on, now that I am actually doing it, it's not really that complicated.

Some CSS made the javascript I used to use obsolete. I used to use javascript for image rollovers, but the CSS hover state made that unnecessary. Reloading content into just one portion of a page however is useful. I wanted to make qwote.com more dyanmic, so I figured out how to make javascript reload the randomly displayed quote every 10 seconds. It's not a smooth transition, but it works. I'm going to see if I can use some jQuery to smooth the transitions out and make sure the container divs grow with the height of the random div.
