/r/talesfromtechsupport /r/maliciouscompliance and /r/prorevenge always give me a chuckle.

r/Aviation and r/KerbalSpaceProgram equivalents would be welcomed by me.

r/liveaudio r/mixingandmastering r/bitwig r/ableton r/ethereum

all of the Linux subreddits I browse + r/selfhosted, r/homelab, r/datahoarder.

all of these seem like easy fits for the fediverse.

/r/trackers and /r/opensignups. the private torrent community is thriving.

Ham radio already exists, but I hope it blows up.

Powerlifting would be great. It has a decent following on reddit. I created the community here so we'll see if people move over.

Oh shit, am I a niche communities redditor already feeling anxious about losing all my anonymous internet peeps.

r/vxjunkies - Although that sub is most fun when randos stumble onto it and get confused. Which might not work as well in Federation world.

r/worldbuilding, r/loremasters

r/TolkeinFans. Discussing the legendarium on a scholarly level.

r/nsfwworldbuilding (which is a great place for thoughtful, mature, intellectual conversations about really creative ideas like quantum pregnancy and all male Orc societies ... and THEN pictures of nude bee women leaking honey from their boobs).

r/magicthecirclejerking, r/linuxcirclejerk, r/whowouldcirclejerk - these subs are my go to "I need to laugh" subs.

r/AskHistorians. What can replace this awesomeness... like ever?

r/ShermanPosting. Make this angry leftist feel like a burning patriot.

r/LateStageCapitalism. I need my angry leftist anticap memes.

r/StableDiffusion

r/Swahili? It's a beautiful language.

r/ImaginaryDerelicts... Here is a hauntingly beautiful rabbit hole for you to fall down.

r/PrintSF... it's literally how I find new books to rea...listen to. I consume audiobooks at a terrifying rate.

r/Podcasts because see above.

r/Qubes. I like my linux like I like my lovers, paranoid and with DID.

r/HomeNetworking

r/AskNetSec and r/OpSec

r/FifthWorldProblems and it's multiverse of affiliates, including r/MadMudMen and r/EnglightenedBirdMen

r/Daddit. I posted my "Here we are at a playground for the first time" pictures 12 years ago... I was looking forward to reposting those alongside the graduation pictures in 4 years.

r/WitchesVsPatriarchy. Yes, I'm a cishet white man, fuck the patriarchy and fuck toxic masculinity.

r/ChaoticGood. This sub makes me happy.

Is there seriously no r/WhoWoulWin equivalent? That boggles me.

We also REALLY need something like r/findareddit, if there isn't such a thing yet.

Textbooks! (/r/textbook) :)

r/shittysuperpowers is pretty fun. People trying to make useless, or, preferably, even worse, superpower, and people in comments trying to make it actually OP

I'm new to the whole fediverse thing, but - if you've got an interest in a specific, uh... Sub? Fed? Community? Why not create one yourself?

r/anarchychess. Where else would I get seventeen unoriginal en passant jokes a day?

ShermanPosting

r/outside. That place is such a needed mental break.

I miss the retro gaming and computing subreddits, and I miss the circlejerk subs, they're comedy gold.

not a niche, but not on lemmy -> r/Pizza !!!
r/BarefootRunning
r/cheesemaking
r/freebsd
r/zfs

r/superbowl

I wouldnt describe it as niche, but Pathfinder 1st Edition.
