I did not like this book. It is repetitive, hard to follow, and strangely vague, especially in the activity instructions. It seemed as if the authors had never written a recipe or a list of instructions before. Other than the instructions, throughout the rest of the textbook, it felt like the authors didn't want to land on any opinion or guideline too hard. My guess is they were worried about the industry and technology changing and making their advice obsolete. In that case, write a blog—not a book!
