You don't want people judging this excellent book based on few language quirks here and there.
I used Lyx because it enabled me to focus on the content without all the markup text. Writing Latex in Emacs can reduce the distraction, but not enough. I just wanted to focus on the content at the time. Learning Latex is difficult enough, learning how to use the major mode at the same time doubles the difficulty.
Obviously, I still use Emacs daily for writing code and other things. Just not for writing book.

If this was intentional - well played. If not - thanks for the unintentional demonstration of Muphry's Law :)
[ten seconds later] Now scanning my own post really carefully for misspellings and grammar errors ;)
From just skimming through a few chapters I can completely understand what the author is saying but the grammar is jarring and pulls me out of the book.
Hopefully the author uploads the LaTeX source files to the repo soon. Grammar fixes are pretty trivial.
