Sharp eye, pton_xd! I’ve definitely developed a (probably excessive) fondness for em-dashes and lost track of how liberally I sprinkled them throughout the post… Hard to have fresh eyes after staring at my own words for too long.
How is it you end up sprinkling them? Have you key binded n dashes to type m dashes instead? You have an editor that auto replaces two hyphens with an m dash?
