Social Bookmarks

I registered for Delicious. I've used it for the sites I added on, but really still like my Favorites, where I have files organized by topics. If there were a way to organize like that on Delicious, I'd use it more often, or almost exclusively, since I like the toolbar that was added on to "Links." (Or, I just don't know how to do that on Delicious?!?) I'd recommend this to friends who I know use a variety of computers in their daily lives...they could then find their favorite places where ever they are. Nothing really "shocked, elated, or amazed" me. I could see this used with students as they research topics and share their findings.
