I’d have to think about the last point, but you’ll find political insiders, prestige academics, think tank types, and mainstream journalists still writing their threads and having their arguments on X. 1/

Some (who aren’t on the right) dislike that they are there, most don’t take tech ethics seriously and let their annoyance at the sanctimony of people (like me!) who tell them they are doing something wrong psychologically justify digging in. 2/

Which you want to do anyway if you are interested in prestige or career visibility, because X remains where the relevant conversations are. BlueSky has critical mass enough for “engagement”, but outside its smallish user base it remains, for now, a backwater. /fin
