Amazing idea but the book could be better executed
The concept of sketchnotes is fun and revolutionary. A mix of techniques from infographic, lettering, journal etc. It's simple, cheap and very fun for your notes, learning, teaching and organizing. The book is fun to read and very insightful. But it could advance the insightful part. Most of its content is dedicated to show how amazing are its various colaborators and what are their approaches towards sketchnotes. There are even exercises to do. But with these lot of artists a library with sketchnotes elements would be very welcome. You can easily find these elements at the internet and even understand the concept in a few "metasketchnotes". But what is the point of a book then?
