I think part of the algo was authors trying to make more tweets diminish their visibility so there's a limit to how many tweets per day they can do on their page before it gets nerf. The rationale was trying not to flood a follower's feed with their recent posts and give way to other posts. I understand this idea. I've unfollowed some hivers in the past because they posted often and used the platform like twitter, not their fault just not the right visibility meant for Hive.
