This was a big issue for me. Some people I followed would constantly post, so your feed, over time, simply becomes whatever those extremely online users post. It becomes less of a "balanced media diet" if it favors people who are always online. Of course, you can just stop following those people, but you really don't know how prolific someone is when you first follow them.
I remember seeing someone post a prototype of a view of the feed that instead treated it like a messaging app or RSS feed where you'd see a list of posters sorted by most recent post date first. That way, you could just click on a profile to see all their posts in chronological order instead of a mixed feed of everyone's posts. I thought might be a better way to go.
