With Y Combinator application season in full force, this seemed like a topical and timely read. The image of the 'cover' gave me the impression that this was a work with some depth to it.
Let's get the negatives out of the way as a Caveat Emptor:
* This is a 49-page extended interview, and that is being charitable (see next item)
* Actual content is less than one would expect from page count due to random extra text padding each section
* The formatting was obviously not reviewed by a human with even minimal aesthetic taste, because visually, this booklet is a mess. The very first chapter starts with a sentence that's missing the first few words.
* Links are highlighted but inactive. If you're going to highlight in blue and underline something, it had better be clickable and lead to the referenced content. Every such item I tested in this volume was inactive.
On the plus side, the interviews were interesting and included insights I had not seen elsewhere.
Overall, the value received was not equal to the $4.99 I paid. Charging under $2 for this work, the equivalent of a single long-form magazine article, would be more appropriate.
