There are some great communities of obsessive hobbyists here like !Selfhosted@lemmy.world, and if you throw a brick in any direction you'll hit two Linux nerds, but reddit has /r/sysadmin and other infosec groups that have large numbers of industry professionals - and no amount of enthusiasm can substitute for real-world experience. I miss the conversation from people who spend time writing system security plans, reading NIST documentation for guidance, thinking about remote management for networks that support thousands of end users, and who have to actually deal with the cybersecurity incidents that get reported in the news.

Investment or stock communities.

Personally I'm boring and just invest in broad market indices, but I still enjoyed the discussions.

3d communities like blender, vfx were active, I was getting back into webdesign (for local businesses freelancing) so wordpress was interesting (for the drama not helpful lol), comicbooks was wayyy more active there (I stopped reading when reddit permabanned me, i liked discussing with the ppl reccomending me stuff), fantasy for books, all the drug related ones, rave related ones, nootropics, supplements, etc. Adhd and adhdmemes there was good, thats okay here.

r/collapse

Full of the most pessimistic possible interpretation of climate change events and news possible.

It's here too, but quite dead.

• Niche committees for random movies, TV shows, games, or whatever form of entertainment. It was pretty cool having communities for The Crow, Hellraiser, iZombie, Xena, Due South (who here even knows Due South?) and basically just whatever the hell you can think of. Even specific bands, to throw music into the entertainment mix.

• Fashion based communities like Alt Fashion, Goth Fashion etc. I think communities like that would thrive here because NSFW is kept pretty much separate from most instances, so it would help keep away the porn brain commenters and OnlyFans bots. Also things like hair and skincare style communities. You could find really niche shit like even communities for advice specific to hooded eyes.

• Feminist slanted communities with active discussion. There are a couple of communities where probably the moderators are keeping the lights on by posting articles occasionally but beyond that, they're ghost towns. I'm honestly surprised that more people from these sorts of online communities haven't come here yet because Reddit in general likes to "both sides" this kind of conversation. While it seems generally more acceptable here to get off the fucking fence and walk around on the left hand side.

I miss there being a lot more Swedes around in the Swedish community. There's >100k+ on Reddit, !sweden@lemmy.world has far less active users and a large chunk of the posts are from me.

One for my model of car. One for native plants in my area

Tbf, most I use especially since I started ignoring news and politics... Chinese, Buddhism, art, yoga, poetry etc. Local city subreddit. Everything "humanities" is sparsely populated here even though I try my best to get the ball rolling. I still use reddit for some of this.

None of the Japanese communities actually migrated over (for those living here, such as the finance one), which is sad. I'm still hoping they eventually do. Until then, unless law and taxes become much easier (try doing legalese in your non-native language that has thousands of characters and tons of Jargon), I still go there for that. Same with ALTTPR, unless it has some community I haven't seen yet.

r/suomi, r/zombiesurvivaltactics and r/samharris

There was a sub i think called r/daily3d that offered a daily prompt for users to create in 3d modeling software like blender. It became inactive years ago when the moderator who offered the prompts stepped down and set up a bot to come up with it instead. It was never huge, usually 10 entries a day at its peak, but that was a fun sub to check in on every so often. Some users were really good, and before the bot took over, the mod offered prompts that encouraged user interpretation and creativity.

I miss r/oura as I could dunk on oura for enshittification. We all could. And then we could collectively decide what else to get.

I think there was an r/redhat too, but that was full of "how do I quit vi" and left no room for debating what should replace Systemd (I vote inittab but there was a minimalist just-enough-lennart crew that made a good argument for a stepdown so people could get some distance and see the pain objectively and get over the sunk-cost).

I like r/pics but I was permabanned for - as far as I can tell - an "and my ax" comment.

That's about it.

I miss tankporn, there aren't enough images of vehicles that can kill me in my Lemmy feed.

Writing prompts. It's here, but it's unpopulated. Tbf the Reddit one wasn't super populated either, but that's where I did a lot of my reading.

ebike/ebikes. energy. endlesswar, internationalrelations, aww.

r/morbidquestions. I don't think it's coming here any time soon as it's a moderation hell and lemmy doesn't seem very into morbid stuff.
