Not going to speak to the content of the blog post, but I want to address something from the beginning.
> Every post is either political ragebait, recycled "funny" cat videos, "Am I the asshole for divorcing my husband after he killed our two children while drunk and high?"-type slop, or tired wojack memes.
The trick to Reddit is to audit your subreddits. There are thousands of interesting, well run, topic specific subreddits. Find communities around your interests and only subscribe to them. Get rid of the default ones that are mostly just cesspools these days.
Over the years I've cultivated mine to include several book series and authors I like, 3d printing, homebrewing, etc.
The other trick is to avoid the Reddit app. Use https://old.reddit.com, even on mobile. It's still the best way to use Reddit.
