del.icio.us

Although I did not sign up for an account, I think this site would be great for teacher to use. I spent some time looking at tags named health and exercise. There were a lot of sites that had fitness ideas or routines. There was even a site that had a program named cron-o-meter that helped track your caloric intake. Teachers who use this could find a lot of lessons and share many ideas with one another. You can find a bunch of different topics and interests on this site as well. Whatever your hobby, it is probably on del.icio.us. This site also allows you to keep all of your sites bookmarked, and allows access on any computer. This site would also be helpful for any research purposes.
