del.icio.us is a great resource for educators because it allows access to many different types of media. This bookmarking site not only allows one to save the sites they have visited and like in an organized fashion, but it also provides links to other, similar sites.
Some of the bookmarks on my site include topics like:
1. Art Education
3. JOLT (Journal of Online Learning and Teaching)
4. The OWL at Purdue for proper citation
5. College Magazine
6. Links to research databases such as JSTOR, etc.
7. Other personal links I can't help but enjoy! (perezhilton.com)
