If you haven't come across the IMSA (Illinois Mathematics and Science Academy) projects before, I can heartily recommend that you do. It is now under the direction and banner of 21st Century Information Fluency.
The latest material that I have had a brief look concentrates on Web 2.0. There is a comparison chart between Web 1.0 and Web 2.0. here. Also material on digg, twitter, delicious, Google bLog Search etc. Very useful for teaching ideas.
