I am somewhat amused that the author seems to me to emphasize the peculiarities of their communication styles when the author has such downright awkward, disjointed and mashed-together style. Eliezer's faults do not include lack of facility with paragraph structure.
In addition to what gwern said, it's worth bearing in mind that Harper's is a very literary sort of magazine, and its typical style is thus somewhat less straightforward than most news.
Cover title: “Power and paranoia in Silicon Valley”; article title: “Come with us if you want to live: Among the apocalyptic libertarians of Silicon Valley” (mirrors: 1, 2, 3), by Sam Frank; Harper’s Magazine, January 2015, pg26-36 (~8500 words). The beginning/ending are focused on Ethereum and Vitalik Buterin, so I'll excerpt the LW/MIRI/CFAR-focused middle:
