It's not so much the communities as the number of posts, I open Lemmy and see posts I saw yesterday only half way down the front page.

Communities for specific video games, like /r/wow or /r/ffxiv

I miss the local subs for my city and other local communities around me. They were great for keeping up with what was going on. I can't stand all the pissing and moaning on Nextdoor. There are a couple of Facebook groups but I refuse to install any Meta apps on my phone.

Right now I am missing the hyper specific cat subreddits like catswhoyell and catsinbusinessattire. There are so many that I loved to revisit every 2-3 months and see what was there

For me it’s just the smaller gaming ones that aren’t as active or not here, I enjoyed browsing through specific WoW (this isn’t so active), ESO or Diablo subs.

My home page is already in fairly nice shape with “general” interests

I miss the niche trade subs, like r/electricians, r/construction, and r/machinists. Tons of great content on their subs that just isn’t here on Lemmy since most people on those subs don’t skew as techy as most Lemmy users.

Still not worth supporting Reddit though.

Ask Science Fiction, Who Would Win, The Maw Installation, and similar discussion boards for in-universe questions about fiction.

For those who aren't familiar, Ask Science Fiction (more accurate parsed as Ask Science: Fiction) is a board for asking and answering questions about fiction from an in-universe perspective. Questions and answers don't necessarily have to be role-played, but they should assume the internal logic of the universe in reference. Answers from an out-of-universe perspective ("George Lucas didn't decide that Darth Vader and Anakin Skywalker were the same person until later") are against the rules, though there's some allowance for media that's super-meta and can't be answered otherwise.

Who Would Win is a board for posing hypothetical scenarios, often but not exclusively about fictional characters or factions. Think "Who would win in a fight between Superman and Batman?". Evidence in the form of references to specific canon media is encouraged.

The Maw Installation (and similar places like the Daystrom Institute for Star Trek) is essentially Ask Science Fiction, but specifically for the Star Wars franchise. I find that boards like this can encourage interesting world-building that makes the original text feel richer, as well as more in-depth critique of the text as media.

I'm sure some of these exist in some form in Lemmy, but I'm still looking for them!

Not missing the subreddit itself, but /r/tvtoohigh is a great symbol for how even the most obscure niche subreddits had a steady flow of content.

Best of Redditor Updates 😭

Trade communities like construction, electricians (my trade), and oshaviolations.

Daddit. It was such a wholesome and helpful community

The art subs, like r/art, graphic design, art nouveau, and all the AI art subs. I was mostly a lurker on those ones but they were really great eye candy.

Also things like earth porn and the nature subs. Was nice to see cool places in my feed.

And the local community subs. I think that will take a long time to develop (if it ever does). I used to get a lot of news on city events from Reddit and without Boost on my phone I'm feeling out of the loop

I miss all my fun niche subs. Like mirror forsale, were it's just funny pics of people who sell mirrors or take pics in front of mirrors.

Purple coco, sub for plugs in strange places.

Chairsinwater, its chairs in water and the flair was always NSFW.

There more but those are the top ones I miss.

Battlestations exists, but has no content. I just made the first post in order to help stir up some engagement! 😃

The subresdit /r/frugalmalefashion was really incredie for a while there, but it thrived in users posting good deals regularly and fair moderators keeping out inappropriate content (i.e. scams, predatory subscription services, and comments like "this isn't truly frugal!"). /r/buildapcsales was the same way

Writingprrompts. Such excellent quality content there.

The subs for games like Street Fighter, the sub for fight sticks, the kind of semi-niche gaming communities that snowballed because of Reddit's ubiquity

I miss aita - I'm not sure if there's a similar one on here

A lot of craft subs, r/embroidery, r/weaving, r/pottery etc. Also r/twosentencehorror.

r/NFL, r/CFB, and r/Hockey. They all kinda exist here but are nowhere active enough.. I miss game threads with thousands of comments.

AskHistorians

I miss r/badtaxidermy It's my weird joy in life to see terrible taxidermied animals.

MaybeMaybeMaybe, OddlySatisfying, ThatPeelingFeeling, CrabCats

A bunch of morbid and medical subs like morbid curiosity, medizzy, medicalgore, thegrittypast. I always have found those subs super interesting and filled with discussion about stuff I don't usually encounter in my day to day life so I've been missing that.

1. Personal finance, the EU version of it and the German version of it
2. Women centric communities

r/korea, r/TwoXChromosomes

My hometown..... great community on Reddit. Pretty much zilch over here so far.

The dry-herb vaping communities haven't really transitioned very well, and I'm too lazy to get back into proper community building and moderation after having all my accounts permabanned on reddit. For now I am just sticking to the 420vapezone discord.

Prequelmemes, renfaire, antiwork, bikinibottomtwitter, raimimemes, insanepeoplefacebook, oldpeoplefacebook, Disneyvacation/notdisneyvacation, earthporn, novontextpics, marvelstudios.

My local city's subreddit. Someone's made one but no one is posting. It was the main way I found out what was going on.

There's a Pokemon Go subreddit called TheSilphRoad that was basically the place for in depth discussion on the game. Such subs here have been quiet and shallow.

r/noncredibledefense. There are a few inactive Lemmy instances of it and the Discord server is cool, but they both pale in comparison to the subreddit

stupiddovenests

I still miss some of the more niche music subreddits, (updating this as I discover relevant communities)

• /kikagakumoyo
• /Krautrock
• /psychedelicrock
• /nearprog
• /zappa - !frankzappa@lemmy.world

Linguistic humor. I know it exists in the lemmyverse but it's not active

WhitePeopleTwitter

The grimdank here is inactive. I miss all my Warhammer 40k faction subs, distressingmemes/surrealmemes, and all the extremely active gamedev subs.

All the niche anime subreddits I frequented. I'm not really a creator myself and I don't think there's enough people migrated to this site for someone else to start posting about PreCure news or similar.

I miss the data analysis subs

I kinda miss collapse and acab for doom scrolling.

r/mls and r/soundersfc

There is an mls community but it doesn't get a lot of traffic.

Seems like all the main ones I subscribed to on reddit are already here in some form, I'm hoping AskHistorians comes on over. There's two more extremely niche communities related to US immigration that I'm in which seem unlikely to ever make it here, but we'll see.

A pokemon go info and discussion community. More r/silph less /go .. some magical middle ground.

Where's stupidfood? I need ideas for dinner!

/r/midjourney

r/PWM_Sensitive

It has less than 1000 members for a very niche topic. With the subreddit so small I doubt it would start here.

/r/Skincareaddiction, /r/EuroSkincare, various fanfiction subs, /r/Medicine, and a lot more.

Reddit has SO many niche communities that have built up a fairly large amount of information over time. I'm determined to stick to Lemmy but it sucks to lose all that knowledge. It's going to take years for Lemmy to build up.

Most of the technology subs I followed have migrated to some degree, but I've noticed a lot of "normie" subs are still stuck. For me in particular, r/Writing prompts, r/nosleep, and r/YoutubeHaikus are sorely missed.

The anime community. Seems awfully dead over here on Lemmy. :/

/r/fitness. I know it sort of exists but the mods and the daily threads and wiki etc are awesome and I miss it.

Dragon Age. I need somewhere to bitch about not having news despite being promised news back in November (like goddamnit Bioware, all we want is a trailer!)

UK focused casual discussion and news.

There's a very small amount, but nothing like there was on Reddit. It's the only thing I miss.

I miss r/marijuanaenthusiasts, which was so named because weed enjoyers had already claimed r/trees. On a search, I see there has already been a "trees" community on Lemmy for a while now (more than one - because of course), but I turned up a big fat goose egg when looking for its arborism-centeic counterpart.

I miss communities sharing news about the attack of Russia on Ukraine. I was mainly browsing these subs: r/ukraine, r/ukrainewarvideoreport, r/combatfootage, r/ncd Non credible defence seems to be active but the others are pretty empty. These subs had about lets a ton of posts every day

HighStrangeness :(

Warriors, watches, and Star Wars

r/bertstrips

I'm addicted to cats, so the 30000 varieties of cat subs mainly.

r/anime_titties ( :-D ), r/fountainpens, r/chessbeginners & r/chess (and maaaybe r/anarchychess) r/moebius and r/moebius_giraud_study :-/

Edit: the old r/madlads was nice, if someone could revive it ^

r/hackintosh NGL, its such an absolute waste of time. But it’s like a puzzle you feel you must complete…

Ididntknowthissubexisted

etymology and stoicism, but I lack the expertise necessary to moderate or kickstart either

Redneck engineering

yoyo and riddim dubstep

Christianity, Gentleman, BulletJournaling

/r/scalemodel

Something to do with systems integration (PLC, fanuc we're a couple subreddits I was subbed to). Also I miss the BMW Z4 sub, seeing new owners pop up, helping others with fixing stuff on their Z4, etc.

A few subreddits I were in were from Hetzner Online (r/hetzner) and Google Workspace (r/gsuite) which I did not find an equivalent for yet. r/armbian and r/armbianusers were mostly secondary since there was/is no interest in moderating those from the official project side. However was reading there from time to time.

I miss r/worldjerking. To me, it was one of the funniest niche subs on reddit.

Daddit!

r/latinopeopletwitter

Macgaming, realestate, Massachusetts.

They exist on Lemmy but verrrrrry quiet

conlangs and neography

Swords and legorockets

Communities You Check Out. Some the old subs on community/magazine style.

I think the link didn't work. Here it is https://lemmy.world/post/983150

AITC and legslcatadvice

r/RomanceBooks There's not really a replacement for it that I've found on Lemmy yet

jailbreak, PS4deals/PS5deals

I miss the sporting communities on subs like r/nrl where there would be thousands of posts on each game thread.

r/visiblemending r/fromscratch r/vermiculture r/TwoXChromosomes

r/hockeyplayers
r/hockeyjerseys
r/Canes
r/nin
r/weimaraner
r/pearljam

I'm missing a few, but those are the first that came to mind

Teaching, teachers, TESOL, international teaching. Basically just a support group for struggling teachers.

r/whatisthissnake, r/subgenius, r/herpetology, r/bash (it is here! But it needs more users!), r/gpgpractice (not that I need it but it helps new gpg users), r/gameboy

Probably more but that's all I can think of right now.

There are transplants here on Lemmy, but few subscribers, and few contents. Some likely would remain that way.

It got nuked on reddit, perhaps with good reason, but I do miss watchpeopledie

And the nsfw stuff, even on lemmynsfw.com , is decent, but hasn't quite reached critical mass yet.

r/doom

r/aeiou

r/okoidawappler

r/spengergasse

The last three are very small comunities, so I'm not surprised, but I don't know why there isn't a larger doom comunity
