I read it but it's a mind dump that's not well structure so it's hard to follow. If asked I couldn't give you an answer to the title. I still don't know, " Why it's hard to buy things that work well." He has a lot of citations and footnotes but if it's hard to follow then the essay becomes a bunch or random thoughts which get condensed into the title. I suspect that's why most of the comments relate only to it.
