Being a Internet pack rat has its downsides, you squirrel away all these links in your del.icio.us account over time and then you check on a link one day and find out that it is dead.
Fresh delicious is a neat tool that remedies exactly such a situation. Fresh delicious is written in Java and runs on any platform that supports JVM. Once you enter your username and password fresh delicious will check each and every link in your collection and report back on pages that have been moved. This is the best tool that I have seen so far that allows you to organize your bookmarks and weed out ones that don’t work anymore. The official del.icio.us Firefox extension should have a feature like this.
