Continuing on the issue of organization...

With the ease of finding information internet, many people, teachers included, come across the issue not of finding information on a site, but finding that same information on that same site again later on! That's why this site is so useful. Once you create a free delicious account, you can add any URL to your account. Not only that, you can add tags to organize your links to easily find related links. You can even share your collection of links with others.

Not only can this be incredibly helpful for teachers, this can be a great tool to recommend or require of your students as well. When they are doing research, have them organize their links using this tool so that they and you can easily go back and review the sources. Sometimes, finding good, reputable, scholarly information on the Web is more difficult for students than using the information gathered.
