I think this is a great book idea, but I think I want to first discuss the objectives for the book, especially before discussing the potential chapters. Blogging is a wide topic, as well as education, so what objective do we want to have in writing a book? What is the expected audience? Will this be more academic or more practitioner focused? Do we want to book to be an integrated whole or have chapters that are somewhat unrelated (save blogging in education)?
What do you think?
