Subscribe to magazines that you want to follow. In setting, change your homepage to 'subscribed' (or whatever it is named). Then only scroll your subscribed communities.

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.
