They'll come, I'm sure, but many craft and hobby-based subreddits, including r/wood, r/cardistry, r/MUD (or MUDs?). I'm looking to external sources for that type of learning new skills or topics.
I don't really care for endless memes and shit posting, but deep content takes more time and effort, so patience seems necessary.
R/leaves has been a mixed bag-- lots of repetitive questions, but also some amazing and human stories.
I feel the same regarding the memes, I used reddit mostly for the niche hobby subs. Lemmy seems to be in the stage reddit was about ten years ago; where it's mostly tech/programming focused in the niches, but I imagine that will expand over time .
