Coming from a third party reddit app, my front page did a good job populating itself with posts from less busy subreddits even though there were proportionally WAAAY more dead posts from /r/pics than from a smaller subreddit. Kbin seems to be showing waay more posts from RedditMigration and priacy right now because of how busy they are. Is this just because there isn’t enough content on kbin yet, or is kbin lacking a way of balancing what is showing on /subs?
I don’t think this really solves what OP’s talking about. The “Reddit front page” actually is just your subscribed feed. And that feed does have a problem where essentially only your one or two most active communities utterly dominate it. Posts aren’t raised relative to the activity level of the subreddit, only globally.
So just subscribing and block communities/subs/bins/whatever doesn’t actually solve this.
