https://sub.rehab/ has a list of a lot of popular subs that have moved to the Fediverse!

r/AskHistorians, r/FrugalFemaleFashion, r/linux_gaming, r/oldhagfashion, r/rabm, r/SkincareAddiction, r/WitchesVsPatriarchy

A lot of fandom-specific subs! With the typical main sub/meme sub/nsfw sub trinity, I’ve seen the main subs show up here with minimal activity while the meme and nsfw subs are nowhere to be seen. A lot of the big default subs have come here, but the fandom-based subs just exist as tiny communities with several thousand times less subscribers and nowhere near enough content to regularly show up on my subscribed feed.

r/Writingprompts, I loved many of the short stories people posted there.

Redneck engineering

Boring dystopia, lost generation, anti-money memes, class consciousness memes itp.

Surreal memes, void memes, deepfried surreal memes, 5’th world pics itp.

Furry_irl, yiff

2visegrad4u

Redneckengineering, unket, middlyinteresring, odly satisfying, swedish problems,

Would love to see /r/dota2 move, but the mods there are overwhelmingly against it, and the people are split 50/50. !dota2@lemm.ee is almost exclusively populated by me

BestofLegalAdvice always had funny commentary on LegalAdvice

HFY. I just love the idea or rather the genre I guess? I also would love to see the old content archived. There are some treasures in there, I would hate for that to get lost.

Would love if the geopolitics people of anime_titties could move over, a lot of them were supporting the protests and may have considered making the jump. Right now, the only geopolitics community that I have found has 3 subscribers… Also wouldn’t mind at some point to have a meta community aggregator like SubredditDrama, HobbyDrama or BestOfRedditorUpdates. It makes for excellent reading material while on the toilet.

r/badmovies <- home of truly bad cult films (think movies like The Dirtbike Kid, and not just “I just turned 14 and watched Starship Troopers for the first time and don’t understand satire or who Paul Verhoeven is,” which is what the sub has basically become on reddit over the past 2 years)

r/r9k <- random gay leftist memes

r/animecirclejerk <- Anime is great, but what’s even better than anime is hating anime and the people who watch it for being degenerate pedophiles with poor media literacy (which is what most of them are).

r/trees <- weed lol

r/politics <- so that people who are too young to vote can share their political opinions while skimming the headlines and not reading the articles posted.

r/manga <- specifically links to new one shots and updates on when new chapters have posted, with discussions

r/selfhosted <- this one probably already exists in a few different places, I just need to find it.

r/comicbooks <- so people can complain about comic books while never actually reading any of them

r/todayilearned <- so people can spam mundane trivia from wikipedia you already know

r/amitheasshole <- so people who are assholes can try and convince other assholes online that they’re not the asshole in their relationship.

r/leopardsatemyface <- for schadenfreude

r/EnoughMuskSpam <- a place for people who hate Elon Musk and other annoying billionaires to gather.

Loved all the circlejerk subs that existed for the communities I liked on reddit, often even moreso than the main sub lol

I’d love to see r/techsupportgore, r/spicypillows, and r/redneckengineering

I need specialized communities for specific types of cat pictures. The Internet is a series of tubes and they should be filled with cats like they’ve always been.

Also game-specific subs. Those two categories were the majority of my Reddit usage.

I know it’s unlikely but ask historians, the moderation required is unreal. More realistic would be bestofredditorupdates for all the mindless drama reading.
