If you spend all your time digging into the corners of reddit, the niche hobbyists' zones, it's still pretty useful. But it is a constant fight against entropy and the rubes.
Oh yeah no doubt. they're informative, helpful, and good for legitimate discussion. It's just such a shame that the broader subs that aren't niche happen to be so toxic.
I use RES to filter away more than 200 ugh subreddits from r/all.
I think I'm nearing 2500 filtered. It's actually a nice place to visit now.
I find they create more crap new ones than I can be bothered to filter.
Can you maybe have a pastebin of such a list? would be very useful
