FutureLab lists Coming of Age... on its list of resources on its blog. Also, I forgot to mention: I'm dead "chuffed" because Graham Wegner is going to contribute too. He has done some good stuff, Se his K12 Online presentation, for example.
I also meant to mention Kathy Cassidy's blog. She does some great stuff with young children. There is a great video interview of her too, called Telling the New Story -- which also happens to be the title of her chapter in the 2nd edition.
