> Long-form written works tend to have more room for breadth, depth and nuance. I find that's where much of the value sometimes comes from, e.g., I didn't get anything much out of the main text of the last non-fiction book I read, but three of the footnotes introduced me to other sources that did turn out to be useful for my work.

All of this is why I strongly favor reading. Well written books are just so worth sinking the time into, and then you have references/bibliographies. Yeah, you need to do something instead of "reading all the time" (stramwan from the article), but sometimes doing it correctly, or even just better, starts with a good book.
