This. I find a bunch of ghost accounts in personal followings. Publication followers seem more solid, but still, there was more opportunity for discovery before membership. I still do my discovery the old way too, going to writers I follow, delving into comments, but that path used to be wider. Now I enter through a tab on my homepage instead of the whole feed. I never even bother with the ‘Medium thinks you might like’ sections save to occasionally confirm that they pick nothing that interests me.
