Moldbug writes at insane length, and yet always very readably.

In that the individual sentences are well-formed. But these days, that's not enough.

(I note that the Urbit manual shows him actually writing with conciseness and precision - so he can in fact do better, he just doesn't want to - though the Urbit security document goes a bit Moldbug two-thirds of the way down.)

It could be a matter of taste. Neoreactionary writing may best be considered a species of poetry, art for its own sake.
