Those are good points. I think there’s a third one, too — reach. If most of us “follow” several hundred people, we see all their posts and recommendations in our feed. Plus medium’s picks. Plus articles related to our tags/interests.
It’s so easy to miss stuff. That’s where reach comes in. We need to find ways to expand our reach, too. If expanding our reach has no results, then it might be one of the other two. But reach is a huge one I think.
