Linux and Star Trek memes. I just don't see them enough.

Ancient coins. There's a sub on Lemmy but it's sadly unpopulated. I miss being able to interface a bit with other collectors, but fuck my ass if I have to go back to Reddit for that.

vinyl records. I miss r/vinyldeals, r/vinyl, and r/vinyljerk.

Not exactly niche but I'd like to see some active gardening and diy communities. The existing ones aren't very active.

Software Defined Radio, Ham Radio, RF Electronics, amateur satellites and Meshtastic.

The only community I am (more than) fully satisfied with here is Linux.

Oh, but also communities like askdentists, psoriasis, etc. Those were pretty helpful on Reddit.

I have a few!

• Vaporwave minidiscs
• Nail polish & nail art
• Skincare
• Fitness over 40
• Greyhounds

The only reason I check Reddit with any regularity anymore is for content local to where I live. There's a few communities on the fediverse for my area, but with only minimal, sporadic activity.

I would love to see more activity around fostering animals, particularly cats. I started !fosteranimals and have participated over at !fosterkittens, but it seems there's not many of us so far.

Edit: No clue why I can only get 1 of the 2 links to work correctly, but FosterAnimals is on kbin.social, and FosterKittens is on lemmy.world.

Hobby machining, automotive, scca.

Maybe I need to think about hosting.....

Anything not tech/Linux related. It's 90% of my feed.

There is not much Lemmy communities for discussion specific/centered around specific entertainment media (video games, anime & manga, web videos, etc)

Back when I’m still on Reddit, I’m used to lurking around a lot of these kind of communities on that site. Community centered around video game franchise like The Legend of Zelda and Sonic the Hedgehog, content creators like Linus Tech Tips and Hololive, and even some niche topics like Windows 10 LTSC and Otonokizaka

Those kinds of subreddits simply doesn’t have any equivalent in Lemmy, and even if it did, it is far far more inactive compared to its Reddit counterpart. To me that is one of the biggest problem with Lemmy right now and kinda could be a reason why there is still many user who sticked into Reddit and does not 100% migrated to Lemmy.

Beginners/basic programming for non-IT. There’s a lot of people that might want to do very simple things with arduino or other mini computers. Python, or even simple Linux tasks, that don’t want to start a whole “Programming lessons A-z” multi-stage class-format learning adventure.

Men's rights, but not like the piss pitt that the Reddit one has, but one that focuses on real men's issues, like how rampant prison rape is in male prisons, parental alienation, forced military service and such.

And before anyone says that "It is men who mostly commit prison rape", well duh, that is obvious, but prison should be a rehabilitation tool, not a punitive one, and especially not a for-profit business like it currently is.

And add the fact that prisoners should be under the care of the government, and the fact that so much abuse, sexual and otherwise is ignored and not prevented is nothing but appalling.

More artsy stuff and more comics, I've only seen Loading Artist over here - if he's the real one.

JRPGs. I live them, but all communities over here are mostly dead - only posting the occasional trailer.

Those were the only subreddits I actually used to frequent, now that I think about it.

Where's the experimental music community at?

more linguistics

more geography

I wish there was somewhere to talk about Counter-Strike, particularly the e-sports scene.

Circuit Bending!!! Moreso, just broad "soldering" representation; places for unique soldering projects. Soldering hacks, solder jobs to brag about, beginners tips etc. Would be cool to have niches within the community too for different "soldering genres" like circuit bending

Cacti/succulents and wine (the fermented grape juice one, not the linux one). There are cactus and succulent communities in Lemmy, but they're not very active, and wine ones are completely dead...

(Original) drawings, paints, sketches made by the OP. Talk about paint, inks, papers, ...work in progress stuff, problems & solutions.

Not that I was into it that much, but I did love seeing pics of fungus on reddit once I found that place.

Random educational posts, like stuff that is actually useful. Like physics lessons.

Lockpicking (along with the ranking system) would be great, plus it was the nicest, most friendly sub I've ever been in

Would love to see more crochet content, there is alot of posts in the knitting community here, but the crocheting ones feel dead.

I wish we had a super active watch exchange like reddit.

Programming languages. (Not programming in general, but specifically language design.)

Headphones and audiophile stuff, especially IEMs.

It's not even that niche imo, but just more music production content in general. There was an instance focused on this a few months ago, but it seems to have gone and not returned.

On Reddit, you have communities of music makers around theory, various genres, various software, synths, and deals. It's definitely a source of inspiration I miss.

shrimptank, aquariums, various weird animal subs :(

Not a hobby, but I would love to see more mental health communities that address things like anxiety, ADHD, ASD or for the ones that exist to get more traction. The lack of these things is the only reason I return to Reddit from time to time.

More sports like NFL, college basketball, baseball, etc. There are communities for these, but they're not very active.

I guess it could qualify as a hobby, but USB C hardware. There was a ton of good info, and news on new USB C devices, and most importantly USB devices not to buy on the subreddit.

Not exactly a hobby. But lost media/lost wave.

Game dev

Frogs.

Romhacking!

Logic puzzles, esp. variety Sudoku.

Scale radio control cars/planes/drones

Scale "dollhouse" builds

Its a super unpopular pitch but the communities on Reddit for steroids and PEDs were some of the absolute best sources of information on them.

I dont do steroids, but I do use a few compounds that arent illegal but are considered performance enhancing drugs by world sporting bodies and trying to find anyone with practical experience with them outside of Reddit is like pulling teeth.

I need morrowind and portal communities.

My reddit subs I guess were all niche.

Curlyhair and Tampa (dead here, and were getting a little toxic on Reddit)

Cocktails (I mod !cocktails@lemmy.world here, it's growing slowly and organically, doing ok, nice place)

Normal Nudes and Naked Progress (not here and I can't figure out how to set up a community on NSFW, and honestly modding anything NSFW is a slog I don't know if I can handle, certainly not alone)

A lot of the more nish writing sub's like magic building or fantasy writers.

British panel shows.

Blender artists

Pegging
