I agree. The algorithms were designed to increase engagement. As often happens, I don’t think this was done with bad intentions, but it had bad consequences because the thought is incomplete.
The easiest way to get people to engage is to get them angry. This is true here like it is anywhere. I can post something a little rage-baity, and it will get more responses. Unfortunately, the algorithms didn’t take that into account. And it’s hard to undo something making the stockholders millions once it’s done.
