Those subreddits sometimes become a really small echo chamber, and it's obvious its just a minor fraction of a genres listeners. I think everynoise.com and your ears is a way better initial genre exploration tool than Reddit even for genres that have been out there for a while and are still popular and being produced.

For the genres I've been listening for a while or jamming to with my rig Reddit is usually underwhelming and I have more success by starting on everynoise.com or Beatport (which I generally dislike for discovery because their gatekeeping of genres is bullshit) and then listening to new stuff that the label for the artist I found is putting out.
