The entire world: interesting in eng being more productive and interested in more maintainable software. So the first 2 sections are interesting.
You then chase them with a list of assertions with zero discussion as to how they make eng more productive, or lead to more maintainable software. Also without even a hint of why people eg prefer not defining styles inline (protip: fun at first. Now try changing one of them... have fun reviewing 3000 inline bits of css.) Like the industry settled on certain things for a reason, and you don't even attempt to engage with that reason.
You also cite dhh when you like his reasoning and ignore him when you don't. about which, well...
