/r/edefinition small sub with 100ish people that get randomly added and stay until inactive. Internets very different once you recognize names and talk to the same strangers.

Also /r/spidergirls

I founded r/recumbent - then handed it off to better folks once it took off. I still mod r/NOC and r/Apraxia. They'll all die. That's OK.

It's the people, really. Sure there are a lot of memesters and low-value content. But when you found folks that took a discussion seriously and LISTENED and put thought into their replies. The very best was when -after a few rounds- someone I started out disagreeing with taught me something. And I also taught them. Philosophy, AI Art, Music, News, Sysadmin, even sometimes in Politics. BestOf is an obvious big loss.

/r/footballhighlights

If Liverpool played at 2 in the morning in my timezone, it didn't matter because I could avoid spoilers and download the full game to watch after I woke up. Not to mention that I could then share it with my granddad, too.

aside from the subreddits related to my hobbies, i will miss upvoteexxegutor

Local communities. I do not know why, but having people share the same social conditions makes them a warm place, even for gaming communities

the official UTDR subreddits. found some of them here but theyre pretty small (like 20 members or smth)

Tiki. Also if anyone can link me Lemmy tiki I'd appreciate it.

I would say some of the more niche subreddits that would be harder to recreate elsewhere. Plus i used reddit a lot because i stay off of twitter and facebook because those are absolute garbage
