I read all of it while I was supposed to be working.
My thoughts: the guy is right on and really, really funny. True, your food won't be perfect the first time you follow his advice but he states that and tells you to practice. His tips are brilliantly simple.
The MOST useful thing I thought he stated was the observation that there are hundreds of books on wild edibles but nothing on identifying farmers crops and how to tell when they are ready to eat. An average person may walk for miles past ripe wheat looking for some wild yoyodyne berries or what have you. It made me realize I need to find out what crops are grown in the area, when they are ready to eat and how to prepare them!
Reminds me of a story (doesn't everything?). I like to attend "living history" events and at one some renactors were complaining about the corn on the cob they were trying to cook. No matter how long they boiled it it never got very soft and tasted lousy. Turns out they didn't know the difference between sweet corn and field (dent) corn. I know my corns but I can't tell soybeans from cotton or when the local rice should be harvested. Time to learn!
