A work in progress, I have started to categorize and annotate useful sites for education, K-12, as well as some other sites at delicious.com. The site is easy to use and provides a convenient way to categorize favorite sites for specific audiences. As of now, I have categorized sites with tags (labels), but 
have not limited access to defined audiences. I have the bookmarks alphabetized, but the list will grow, and I will continue to edit the annotations to make them more useful. Please let me know of sites worth adding, and keep in mind this is an ongoing project that will require continued maintenance to keep it current. Here is the link to the site to access my bookmarks. Please let me know how I can make the site more user friendly. Suggestions are always welcomed. http://delicious.com/JudyArzt. I see the annotations as way to end clutter! What about you? Maybe you want to start using delicious.com if you have not already started an account.Since writing this post, I have now switched to Diigo.com for maintaining annotated bookmarks of helpful online sources. You can access my diigo account at http://www.diigo.com/user/educ570, and you will a growing list of online sites to explore. Suggest you try http://www.diigo.com/ if you are not already.
