My copy of Will's book "Blogs, Wikis, Podcasts, and Other Powerful Web Tools for Classrooms" just came in. Looks like it's going to be a pretty good read, providing the perspective of an in-the-trenches teacher, rather than just the geek echochamber I usually expose myself to...
The book is definitely on top of my nonfiction reading list (my fiction reading, on the bus ride commute, is currently another Gregory Benford book I'm deliberately reading out of sequence...)
