I do this, but then to avoid echo chambers I do occasional fault injection where I pick someone that one of my feed is at an opposite pole to in some salient, on some axis, and inject them to my feed for a while. Maybe I have something to learn from them, maybe I don’t, maybe they stay on the feed or maybe they are removed. I hope this helps me avoid groupthink.
