At least until recently Twitter was the rare platform that allowed you to get close to a reverse chron feed. They didn’t make it easy but you could do it. It was things like that, lack of a killer instinct that kept it financially marginal. Though some of us know it from a tech perspective it is difficult to grasp the psychological impact of an algorithmic feed. It’s very literally meant to provoke, to agitate. A chronological feed doesn’t do that. That is a big part of the different experience.
