del.icio.us direc.tor
Check out del.icio.us direc.tor for a slick Javascript+XML interface to the popular social bookmarking service. The linked page goes into the detail behind the Javascript wizardry, but you don't need to understand any of that to take advantage of the thing. You do, however, need an XSLT/Javascript-capable browser like Firefox or Internet Explorer. =) Have fun!
