There are a lot of things to criticize about Twitter but it shows a lack of imagination if you think the worst possible thing you could do with a 160MM+ daily active users is give them short form conversation dynamics, and that the other possible outcome is “it burns.”

It is absolutely possible that Twitter turns into a 4chan-esque cesspool of vitriol and hatred but at massive scale due to a gradual frog boil of 160MM+. Not to say Twitter had none of this, but again, it takes little imagination to worry about it getting much, much worse.
