The book has some interesting ideas but by far its biggest and most painful shortcoming is that it is extrodinarily poorly laid out and wastes a tremendous amount of pages space. It is much worse the the same PDF suggests (which is not that good). The poor formatting is so bad that it is barely usable, I spent the weekend rebuilding and it turning into a well orgainzied and laid out print quality 137 page document (down from 411 pages) when i found that the author is selling a well formatted version on Lulu for $20. Why is that version not available here as a PDF? The 411 page version of Afterpeak hurts the eyes.
