@dismantl here’s what i do to curate my Mastodon feed.

1. If anything shows up in your feed you think is not-interesting, go look at that users profile / past posts.
2. If they have a habit of posting uninteresting things (like 4/5 of their past toots were meh) then maybe unfollow
3. This is an easy call for me if they’re one of those that post multiple times a day, every. Single. Day.

This process is a little laborious (especially if your follow list has ballooned) but it becomes second nature as you peruse your feed day to day so just make a habit of it. My feed is in great shape these days thanks to doing this for months. I rarely unfollow anyone these days.
