Thank you (to you and konz (https://news.ycombinator.com/item?id=9705512 ))! I've been wanting to read this, but not enough either to sign up at academia.edu or to read it through that site (I like to read in Preview or on paper). Coming from math, where the arXiv is deservedly the gold standard, I've never understood why other disciplines use these terrible aggregators.
