I started to read this book today after having it on my shelf for several months. The book is written in a very casual, easy-to-read format. However, I found that the organization and flow was not helping me learn anything about arguing effectively. I honestly think that the entire book could be condensed into maybe 1 or 2 blog posts, with more concrete examples and much less fluff.
