They are also very repetitive. When I started reading it (back in 2015 I think?) I thought that they had some interesting info, but needed a good editor to remove at least 60% of the material; many chapters argued the exact same point as the previous chapter, with a slightly different analogy. Also many are responses to other blogs of the time, which also isn't interesting to read in a book since you don't have any context. Very tiresome to read.
