Book from Blog

I've decided to see if I can make one or more books out of material from this blog. I don't have an exact calculation, but my rough estimate is that I have made more than a thousand posts, so probably upwards of half a million words. I am currently going through the blog, making a list of categories to sort posts into, with each category to end up as a chapter or section in a book. Obviously not all of the posts will be suitable to use but, looking through them, I think many will, so I should be able to get at least one book, possibly two or three, out of them.Two question for readers, especially ones who have read the blog for a long time:1. What categories do you think I should use?2. Out of my list of categories below, which do you think most suitable for a book? The ones with a question mark are ones I am less sure of. Climate + other environmental issues Home Schooling (and education more generally) Economics             Law and econ Gun control? Cryptocurrencies and encryption? Law and law enforcement Medical? Politics Trump Republicans less nutty than they are represented as Technological Technology My wish list Science, inference, information sources and the like             Statistics Eugenic and genetic issues. Contraception. Polygamy. History             Adam Smith IP Libertarianism and anarchy Internet stuff and evaluating stuff SCA stuff? My writing? Novels? My travels? Philosophy? Books             Kipling? Orwell WoW+ How to lie with statistics while telling the truth? The FLDS Case Religion? Controversies:  Loaded Dice. Robert Frank Virtual Reality Macro?? Hierarchy Words
