This is great - I have a suspicion that large chunks of high-quality computer science Twitter content is posted while people are in the middle of coding, or doing some other project. Mobile-only was a small to medium barrier to posting good quality stuff (but a low barrier to posting bad quality stuff).

Unrelated though, I don't know why Threads' recommender system is so bad. It's like, the minute it exhausts posts from people I follow, it starts aggressively showing me either 1) "Threads vs Twitter" posts 2) some random political hot take or 3) some combination of the first two, any of which is a huge turn-off for me from the entire platform. It's always been a bit of a mystery to me why Facebook seems to be so bad at showing me relevant content when some of the smartest people in Machine Learning work there (in fact, I used to work on machine learning there and it was a mystery to me then as well). Maybe I just have very atypical usage patterns, or maybe I need to turn off my ad blocker, or maybe (my personal pet theory) the quality of ranking systems is hidden from leadership by many layers of people padding their PSCs in various ways...
