Lol as the person who shilled this into the community I can tell you the chain of events. I heard about the mandibles when it came out from my father. I picked up a copy, read it and liked it. A few years later I went on tftc and mentioned it offhand to Matt and Marty. They took the recommendation. Read it. Liked it and began to talk about it on the show from time to time. More people read it. It became a cult classic in bitcoin circles. This brings us up to today.
