• Eurovision, having a community for people who enjoy the contest as much as I do helps a lot. The Eurovision Discord has listed some Lemmy/Kbin communities so that's good.
• Some label- and artist-centric music communities, specifically deadmau5/mau5trap and Above & Beyond/Anjunabeats. Gonna find me a pop community like Popheads as well I think.
• Polandball, gonna miss those the most leaving Reddit. The comics were fun and the balls are cute.

TwoBestFriendsPlay it was such a stream of seemingly random, but somehow cohesive bullshit

I have already found a lot of the same communities here on Lemmy. I am hoping to find new things that I didn't even know was out there. I would suggest scrolling All and subscribing to things that interest you.

I'll miss the breaking mom / broken mom communities

ShittyFoodPorn, AbandonedPorn, DIWhy, PallasCats, CurlyHair…

I miss:

r/abrathatfits - those folks took it to 11 for helping people find the best fitting bras - no matter your shape, size or orientation.

r/makeupaddiction - as someone who constantly feels like they’re putting on greasepaint and not makeup, the sub was great for helping people get their cosmetics game on

r/skincareaddiction. - a great sub for anyone struggling with skin issues

r/haircarescience - another great sub to help people with all their hair struggles

r/loseit, r/cico, r/1200isplenty, and the more discrete offshoots - great for helping me structure dietary goals.

r/hysterectomy, r/diabetes - because support groups matter (and I didn’t find the Hystersisters very supportive when I first went there, years ago).

r/volumeeating, r/eatcheaply and healthfully - lovely food “hacks”

r/criticalrole (I do hope that we regenerate with Lemmy.world as I believe there is a community of Critters there).

r/aquariums - I used to have an aquarium when I was younger. I always wanted one as an adult, but I have to suffice by living vicariously through other enthusiasts.

r/superbowls - because: owls and because it’s fun to watch the American football enthusiasts get “lost" in January.

There are others (I subscribed to almost 250 subreddits), but I can’t remember them off-hand.

r/linux r/linuxquestions

The community I use most and the only one I still visit reddit for is r/hockey. There are a couple of hockey communities here, but they aren't active enough for them to even show up in my home page.

Unfortunately they were very vocally against a blackout, and they seemed to think all the complaints against reddit were stupid/overblown. So I doubt the users will move here.

I miss starterpacks, Hydro homies and the steam deck subs. Some of these are set up but the communities aren’t very active yet

Redneckengineering, unket, middlyinteresring, odly satisfying, swedish problems,

I'd love to see r/techsupportgore, r/spicypillows, and r/redneckengineering

More than migrate, I want to see the content build. Much of my browsing was looking through obscure threads (in askreddit for example creepiest things online, scariest this, etc. ) and reading comments.

TBH, none of them. Reddit has has a lot of time to make sure the communities have been culled to the most acceptable to reddit's advertisers. I don't want any of that.

Old recipes, colorized history, high strange, gonewild (they need a home too), and white people gifs. Those are the ones I have off the top of my head
