Honestly, a lot of NSFW subs devoted to somewhat niche fetishes. I saw lemmynsfw.com started up as a separate instance for NSFW content, and I'm hoping at least some of these subs make it over there soon.

Nosleep and other horror/terror/creepy things subs and some specific videogames subs

Comics. I don't think a lot of comic creators will start posting here, so can't interact with the creator.

With that, also not sure about editing like bonehurtingjuice.

Also, potentially somewhat nsfw subs dedicated to specific people. Somehow I doubt the Lemmy community in general has much interest in that. Too mainstream I guess?

Cyberdeck & cassettefuturism

Jeopardy for daily show breakdowns

Local sports teams

A few gaming ones, but I suspect they're here somewhere too

Most of my favorites have a discord, but that just doesn't feel the same. Very hard to wade through all that chatter

R/reddevils. We are trying to reform it here but it will take time

All the cat's subreddits

r/castiron r/cremposting r/absoluteunits r/old_recipes all my favorite corners of the internet

I'm really going to miss /r/writingprompts, I've written a lot of stuff for them over the years. Sadly I don't see a replacement popping up here yet and their mods also didn't bother with the blackout protest.

Not ashamed to say trashyboners. Someone's gotta stand up for the trash of this world.

Hey everyone, I just joined 5 minutes ago. Been a Redditor for 7y 2m. I’m actually really going to miss reddit and many of the communities such as r/idiotsincars, r/catastrophicfailures, and well a couple hundred more over followed over the years. I’m hoping I can find more community here though. I never felt connected to the users on Reddit. Maybe it will be different here.

futurology, medicalgore, medizzy, okbuddyretard, surrealmeme,bossfight,chadtopia, internetisbeautiful

My local city subreddit, r/stlouis. The fediverse channels for it are dead but hopefully that will change. Also r/personalfinance

/AskAnAmerican - It's interesting to see what the rest of the world doesn't get about us.

If I’m being honest, I was a big browser of NSFW subreddits and I’m hoping that lemmy will grow and create a space for NSFW communities that are well-moderated and safe.

/r/feedthebeast, I love modded minecraft!

I'm definitely going to miss the true crime/unresolved mystery/paranormal subreddits. I loved the CreepyAskReddit curation.

I’ll definitely miss r/worldbuilding. Lots of people making cool stuff on there.

sports subs probably... and r/anime... ah and r/idiotsincars

EDIT: r/manga too....

I'm going to miss all of my smaller history/archaeology related subreddits.

I participated quite a bit in r/whatsthisbug and r/spiders helping identify bugs (mostly spiders) for people. It was something I really liked doing, especially educating people about how spiders aren't things to worry about. Guess I'll just head back to iNaturalist for that content.

Other than that, more niche gaming communities were a big one for me. r/puzzleanddragons is a mobile game I play often and the sub was super helpful for news and game discussion/guides. I hope it can kick off here.

r/houseplants and r/food. I loved browsing aimlessly through all the pictures and seeing pets in the background.

Where my r/futurama_sleepers at

r/BestofRedditorUpdates I fall asleep reading posts, it's bad (edit, thankfully someone made one here /c/bestupdates)

r/PersonOfInterest because it's my favorite tv show, I'm really due for a rewatch when I think about it

r/FunnyAnimals. For some reason, it made me sleep better at nights. A few funny videos with pets and I could end my day with a smile.

r/Fedora and r/ThinkPad. Those are the two I spent the most time in. I will also really miss my guilty pleasure subreddits like r/gaystoriesgonwild, r/Twinks, and r/GayKink. Haha.

I'll miss the meta subreddits like lostredditors, switcheroo, SubredditSimulator and SubSimulatorGPT2. I'll miss niche communities built around less mainstream games and shows. I'm really going to miss DaystromInstitute and SonicShowerThoughts.

Overall my biggest concern is over the giant stockpile of years of community answers to all kinds of questions. If Reddit falls what happens to all of that? How do we pick up the slack if it does?

r/196 - Everyone seems to have split off into 4-5 different groups, which kinda sucks. r/TwoXChromosomes, r/Lies, r/HuskyTantrums, r/UkraineConflict, r/HyruleEngineering, r/bonehurtingjuice, r/catbongos,

Will miss the AFL (Australian Football League) r/AFL

Forwards from grandma. HI JENICE, HAPPY BIRTHDAY. YOUR AUNT HAD VASECTOMY LAST WEEK AND PASSED AWAY IN HER SLEEP. L.O.L. XXX

bestofredditorupdates, watercolor, embroidery, fitness, fundiesnarkuncensored, cooking.. there’s a lot. This is so sad and I hope Lemmy really takes off. And if it does I hope some of these talented developers make bad ass apps for it
