What are some Communities you recommend checking out and why?

Superbowl
Because the instance is dedicated to pictures of owls and it delivers on that mission. I don't even like owls all that much, but it's like one the last few consistent things in my life.
- !superbowl@lemmy.world for the lazy
  
  Does my link not work for you?
  Edit: The link does not in fact work as I thought it would. I learned something about the Fediverse today.
- Having random superb owls appear in my feed is very cheerful!
- I wasn't going to say anything here, because I've been trying to self promote less now that we're a big enough group, but that so many upvoted this without any kind of promoting felt really nice.
  Especially from someone like you who has stuck around a long time now without even being super interested in the subject matter tells me I'm doing something right.
  I have a hard time thinking I ever accomplish much of anything important, but a number of you have said some really nice things the last week or so and it's meant a lot to me. I try my best to show that appreciation back, and I hope I do that.
  And I'll always argue that even though I provide most of the posts, it wouldn't be a fun place without all of you that do come and comment or just keep the place active and a generally good place to be. It encourages me to keep giving it my best efforts even if I'm not typically a super social person. You're a really great group and I feel fortunate you share your time with me.
  PS. Chicuahtli forever!
  
  Hey fun fact I actually confirmed chicuahtli is actually the barred owl in Nahuatl after finding the word chichtli for barn owl.
  It's still a mess online sorting it out when doing searches for it and I haven't cross referenced versus other dialects.
  Regardless keep posting owl pics. I've been doing Codex research for fun and found a good source. I'll start keeping note of where I find owls and reach out later.
- That was a lot funnier on reddit where there could be only one community called "superbowl" and it was about superb owls. Here on the fediverse, "superbowl" on other instances can still be communities about the Super Bowl.
  
  I'm okay with the tradeoff

Some notable ones I like:
https://lemm.ee/c/internetisbeautiful
https://lemmy.world/c/creepywikipedia
https://lemmy.world/c/til
Mainly because of learning cool and interesting stuff, and sites.
Also check out for more communities;
https://feddit.nl/c/trendingcommunities
- For the lazy:
  !internetisbeautiful@lemm.ee
  !creepywikipedia@lemmy.world
  !til@lemmy.world
  !trendingcommunities@feddit.nl
  
  I wasn't sure how to get these without typing them out. I just used the share link feature. I am using boost for lemmy

!piracy@lemmy.dbzer0.com - because we have booty (like treasure, not that booty) (not accessible on lemmy.world instance)

i'm your stereotypical reddit trio: tech, politics & shiposting/memes so i do communities like badposting or us news & politics and linux and i prefer these over the alternatives because of the engagement.

here's a dead community ran by some asshole mod who never contributes anything anymore:
!howtimeless@lemmy.ml
Essentially it goes through the lyrics of various songs and tries to pinpoint how timeless the lyrics are based on their etymology. The further back in time the song can be taken, the more timeless it is.
Like I said, the mod's an asshole, so just best to avoid it completely if you can

!52weeksofart@lemmy.world. Because it just started and needs contributing artists.
- Hehe, fart
  
  My wife didn’t get the joke but I found it titillating.

!games@hexbear.net is the best gaming community on Lemmy IMO, it's extremely chill there and has no "gamer" brainworms.
- Absolutely adore your pfp
  
  Thanks!

!eleven@lemmy.ml (because it's educational)

!newcommunities@lemmy.world
!trendingcommunities@feddit.nl
!communities@ponder.cat
From those 3 you can discover others
- How did you make those links because they're off site links and I'm trying to figure out wtf is going on in this thread.
  !newcommunities@lemmy.world !trendingcommunities@feddit.nl !communities@ponder.cat

!imageai@sh.itjustworks for it's weekly challenge (voting on the week end)

I might be biased, but I really like !stick@sh.itjust.works. Really fun posting about the wonderful qualities of a good stick.
(FYI, I'm the mod, if you don't want self promotion, I can delete this. But I do think the community is great)
- So that community is great, subscribed.
  On a similar "I went for a walk, check out this cool blank I found" vibe, does anyone know of an equivalent one for rocks?
  I know rockhounds used to be a thing on Reddit but I haven't come across a Lemmy equivalent yet?
  
  I haven't seen anything, but let me know if you find anything or make one, sounds fun.

ITT: people who don't know how federated links work. I'm not joining your instance or searching your recommendation on my own.
@anarchism@lemmy.dbzer0.com because the masters tools will never be used to dismantle his own house.
@selfhosted@lemmy.world because fuck 60+ streaming services
@piracy@lemmy.dbzer0.com because fuck 60+ streaming services
edit: looks like even ! links aren't standardised. What an absolute shit show.
- !anarchism@lemmy.dbzer0.com
  !selfhosted@lemmy.world
  !piracy@lemmy.dbzer0.com
  For links that work.
- Your links don't work with Sync. Everyone else's do.
  
  sounds like a sync issue. federated links don't direct you away from your instance so you can actually interact with the communities being linked to no matter what activity pub software you're using.
  Lemmy users have a bad habit of using local links which are next to useless unless you're on the same instance.

Not this community, because nobody follows the rules of it anymore and just treat it as the default/catch-all community, posting any old thing.
