Do you still not grok Del.icio.us? Well, here's an amazing little AJAX application that provides an alternate interface. Unfortunately, unless you already have an account, it won't help you derive meaning from the semantically ontological goodness that is delicious, but at least you can look at some pictures.
Whenever I see this type of AJAX high-wire coolness, I think to myself - there's a programmer who's way more patient than me! I doubt that anyone over 30 can really do AJAX... too much pain... I myself can't stand writing more than 20 lines of CSS - going back and forth between IE and Firefox to make sure it works... throw in JavaScript, DHTML, XML, XSLT and more CSS, and it would just make me cry.
