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.

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

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.

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

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!

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.

Writingprrompts. Such excellent quality content there.

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

Best of Redditor Updates 😭

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

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.

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

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

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.
