I've quit Reddit off and on over the years, and one of my fears the first time was missing out on news or helpful tips from small professional/hobby subreddits. I ended up building a tool that would email me the top 3 posts from a list of subreddits every day, and that was all I needed to quit without feeling like I was missing out. My tool eventually broke after Reddit's api change, but now I use one called redditletter¹ which does the same thing.
This was exactly the same kind of motivation that prompted me to create a RSS project to allow me to interact with platforms like Reddit/HN/Lemmy in a more low-volume and healthy way, subscribing to just the top posts in my RSS reader with rich custom feeds.
