Check out my new link list on Delicious.com! I like to share links for my students on the orientation blog that I have created for all the English courses that I teach. However, I think I might use the stacking option of Delicious to share educational web tools with other teachers.
The Internet is a jungle. You have to be careful not to let your link lists get too lengthy. Too much information is hard to process and use to the students' advantage. Stacking and categorizing them is a great idea. Including a brief introduction and sharing lesson plans also help others survive in the jungle.
