I think that Delicious is a great tool. I like the tag clouds in the opac and never connected that that was the same thing. I can see putting all the websites that you use often as a bookmark in case you forget the exact names. It will also be helpful as a research tool so that the information is available to all in an easier manner to obtain at any location. I created a book mark on the library's delicious page for the fan which is a website I use daily. Hopefully, I'll make a delicious account and have lists of websites that I can get to quickly.
