> even small niche subreddits are facebook / tiktok tier with low effort meme posts
Completely agree.
There's a few niche subs I hang out in but, for me, the standout in terms of quality decline is r/DIYUK. The difference between that sub in 2019/2020 vs today is stark.
It's pretty common to scroll through several pages of repetitive one-line "jokes" before getting to anything remotely resembling a real answer.
Mods seem relatively inactive and there are only 4 of them anyway, which is nowhere near enough to keep on top of the volume of posts and comments nowadays. Really it needs either a lot more mods, or some form of LLM-backed automation, to weed out the low effort comments.
It's become a bit of a wasteland in terms of a lot of the regular contributors who used to give good, well thought out answers, have tapped out. I complained about this the other week and got downvoted and accussed of "showboating" which, honestly, I'm not even sure what the commenter who said that meant in the context of the discussion that we were having.
It's a real shame because there aren't really any good UK-focussed DIY-oriented discussion forums any more: all the others degraded and became toxic, which is where r/DIYUK won, because it resisted that trend for longer. No more, sadly. DIYnot always stood out as a place that was more about battling egos than providing meaningful help and advice and, although r/DIYUK hasn't gone in quite that direction, it is sadly headed down an equally useless and destructive path quality-wise.
