It's great to read someone who gets web 2.0 and how it can be effectively used in the classroom. His target audience is obviously, but I think his applications can be applied to higer ed as well. Consider how his students, who were studying the book, The Secret Lives of Bees, were able to interact with the author through their course blog. Outside of blogs, Will also talks about how Flickr is his killer online app because of the extendability of being able to include picture notes, titles, captions, and comments. By far the biggest theme I took away was that students (heck even us old foggies) need to learn how to read and write in this new online medium.
