I'd not heard of this book before but "The Edupunks' Guide was written to be a first-of-its kind resource for
the future of education: a comprehensive guide to learning online and
charting a personalized path to an affordable credential using the
latest innovative tools and organizations. This guide is full of people,
programs, and ideas that are part of the future of learning."
They have also released a lovely looking interactive map, a sortable database of educational resources from the book and around the web.
I'm checking out this website for inspiration......
