D&D/TTRPG subs like r/DMAcademy, r/3d6, r/Pathfinder2e, r/dndnext, r/dndbehindthescreen, r/dnd, r/dndmaps, etc.

Subs related to specific games I enjoy like r/Stellaris, r/Rimworld, r/crusaderkings, r/citiesskylines, r/slaythespire

Subs where design and cool information that interests me can be shared like r/vexillology, r/history, r/mapporn, r/dataisbeautiful, r/etymology, r/todayilearned, etc.

Neurodivergence spaces like r/Aspergers, r/AutisticWithADHD, and r/autism

Subs built around a certain kind of joke or humour like r/sbubby, r/expanddong, r/Polandball, r/highqualitygifs, etc.

I support anything creative, unfortunately I'm not seeing a lot of that yet. I build models, dioramas, scratch build buildings, etc.

I was tempted to start a general making community where all disciplines of making are supported, but as far as I can see on the app that isn't an option.

/r/retrobattlestations, /r/retrocomputing, /r/BBS... I'd be happy to mod one, but don't see how to create - I'm new so... I'd love for a BBS (Bulletin Board Systems) and other retro-computing subs. w00t w00t!!!

All the niche communities. I've been here for a couple months now but boy is that what we need.

Loseit, maliciouscompliance, skincareaddiction, halloween, horror, ladyboners, Microdosing, workreform, truecrime, movies

SPORTS! The sports subreddits for specific leagues or teams were some of my most visited. I always hated r/NFL though because the mods only really allowed twitter links rather than legit discussion. I'm going to try and be as active as I can in the NFL and NBA communities here, and I might open some for my favorite teams.

This is actually a great opportunity to organically develop communities like r/NBAdiscussion but for other leagues. I always found reddit to be lacking a real football discussion subreddit, and r/NFL had such strict rules you couldn't even talk about relevant topics, such as EA and the NFL exclusive license (any Madden-related post would be auto-removed and told to post on r/Madden), and you also couldn't advertise an NFL discussion based sub anywhere either.

There's got to be an overlap between Lemmy users and sports fans! I can't be the only tech nerd who is interested in the fediverse and also loves American sports!

r/selfhosted is an amazing community full of passionate people that live for this type of federated community.

I dont know if my niche will quite fit the site yet, but I've followed a lot of animal subs ( crestedgecko, aidke, partyparrot, the twenty thousand cat subs... catsbeingcats of course a favorite ) and also a lot of botany style subs ( botany is the obvious one, houseplants, houseplantcirclejerk, savagegarden, mycology ) and then the unusual to pique interest ( unusualvideos, atbge, designdesign, barbarawalters4scale, hmmmgifs )

Special call out to /todayilearned a /awwducational for giving me fun facts to share with my co workers.

I think if there were master communities it would help appeal to a broad crowd.

I need some more sports communities. NFL, CFB, football/soccer, NBA, MLB, Hockey, etc. A lot of the very niche ones like certain anime (r/onepiece, r/kingdom, r/hunterxhunter) or book (r/asoiaf, r/stormlight_archive) or game (r/deadbydaylight, r/stellaris, r/EU4) probably aren't going to get high enough populations to exist here so i don't expect it. But I need the sport specific ones

This might be controversial, but I think the TwoX communities need space here. Don’t make them automatically appear on the front page, and hopefully their creators and moderators have the tools to keep them space but yeah, this site needs spaces like TwoXSex, TwoXChromosomes, TwoXPreppers, Beyondthebump, Mommit, Childfree, etc. I’m new here but didn’t find any of those on initial glance and like a great bar, you need women to show up and be seen/heard. Give them a safe space (see my comment on moderation tools) to transition to and I bet Lemmy would get lots of people to switch.

Also, to echo another person, we need a “master” list of communities, at least the umbrella ones. For instance /plants could be the umbrella for /botany, /trees, /gardening, etc.

Lastly, this site needs porn. Hear me out before you start judging. Nothing drives technology usage like porn. VHS and digital video are both huge because of porn driving widespread adoption. PornHub needs to spin up a server for its infinite catalog which ensures they get paid but also that minors aren’t being exploited.

Oh, feature ~~Request~~ request, some kind of incognito mode in the mobile apps which lets people view NSFW media without it being in their history. Also the app should disable built-in messaging options while in that mode to ensure fewer bad decisions and bad outcomes from accidental texts of disabled midget porn to various contacts. Just an idea I had.
