I’m talking to Corwin about a 4th Ed, but it wouldn’t come out until next spring I think. If you have any suggestions for additions/deletions, I would love to hear them. I’ll probably add a Tumblr section, but I’m pretty sure I would keep Blogger in there…more ways to administrate who sees what.
Have you thought of going more interactive with the ideas? What if you set it up as an interactive wiki (my suggestion would be via wikieducator.org, but that’s mainly because I am trying to work solely in open education resources)?
