I don’t rely on reddit for any valuable discourse. That isn’t to say there is none but it’s diluted by many one-dimensional thinkers.

For some strange reason, I've been spending a lot of time in r/AdventOfCode this month. ;-)

Mostly it's for general overall awareness of the various things I'm interested in. It's a far more permissive environment for blowing off some steam.

/r/sailing definitely. Awesome community.

The various tech subreddits are also useful. Some others, in no particular order:

r/fire

r/digitalnomad

r/design

/r/bestof is a hit-and-miss but I discover some new subreddits there.

/r/askhistorians, /r/askscience, /r/whatisthisthing, /r/legaladvice (or rather the one specific to my country), /r/manufacturingporn

For anything tech related I stay on HN

All of my favorite ones are banned or removed for one reason or another. For example, one _very_ niche, very entertaining subreddit is gone and it's fanbase scattered to the winds. Died of his death, unfortunately.

I wrote about my favorite software subs recently [0]. tldr; /r/emudev, /r/programminglanguages, /r/reverseengineering, /r/databasedevelopment, /r/esolangs, /r/unikernel, /r/graphicsprogramming.

There were a few more suggestions in the HN thread as well [1] and on Twitter [2].

/r/redscarepod

/r/streamentry

/r/slatestarcodex

/r/emacs

Two here require some explanation: Redscarepod is for folks who listen to the Red Scare podcast, though I’d guess 30% of that subreddit listens regularly. It’s my favorite cultural subreddit.

Streamentry is meditation subreddit with focus on attaining enlightenment.

/r/unclebens

r/commandline r/sysadmin r/datacurator r/datahoarder

Surprisingly good signal-to-noise ratios for all of them.

Specializedtools is great
