/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

iOSgaming and gamingcirclejerk will be missed for me.

/r/anime_titties, which despite the name was a world new aggregator sub that did a great job of not being too euro-centric. The best part that it brought people from many political ideologies and countries, so it was far less of an echo-chamber than most news subs. It still trended left, but it was a good mix.

more of the monster catcher / game subs ( r/yugioh , r/bakugan , ones like that ) . ik that they'll probably come over to here eventually , but it won't feel the same as how it did on reddit .

r/boardsofcanada

r/Icecoast and r/skiing , it's going to suck finding something as good as that again. Especially Icecoast.

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.
