I'm going to miss my local subreddits, like r/toronto and r/askTO. They have (had?) a very active and interesting userbase. I'm going to miss the subreddits for the games I play, like The Sims and Civ. I'm going to miss the subreddits for the TV shows I follow. I'm going to miss the lady-focused subreddits, the cute animals subreddits, the mental health subreddits (which have gotten me through so much), the science subreddits, and the news subreddits. I'm a member of so many communities there that I love. I'm going to miss them all.

I'm mostly going to miss my local subs. It was nice to stay up to date.

It's going to be nice to get out of the habit of grabbing my phone randomly. I really hate that I do that.

i'm going to miss r/duggarssnark, r/askoldpeople, r/xennials, r/talktherapy, r/leopardsatemyface

I miss the Apple related subreddits, that community hasn’t really seemed to move over yet.

r/internet_funeral They have surreal textual art which was pretty cool

I loved reading the stories on r/AmITheAsshole and r/WritingPrompts. Some others that I frequented were r/Bombing (graffiti/tags) and r/Battlestations (computer setups). Deep love for r/CurseOfStrahd and all the little Dungeons & Dragons communities back on Reddit.

illegallySmolCats, furniturerestoration, visiblemending. I love cat pictures and diy type shit.

Gonna miss HFY and Unity groups.

Twilight’s subreddit and my 2 (very dead) NSFW subs.

I don't think that I'll miss any particular one but I'll really miss the more niche shitposting subs like r/okbuddychicanery and r/snapchad

I am going to miss many, one of which is /r/gaybros. I have created [email protected] (/c/[email protected]).

I will miss r/baking, r/breadit, r/rabbits, r/old_recipes, r/askhistorians, r/archivists, r/truefilm

I'm going to miss r/hockey and r/nfl. Reddit was my place to get my morning sports fix. Hoping Lemmy can grow and gain in popularity!

I'm going to miss r/datasets, r/selfhosted and other subreddits that allowed me to tap into accessible niche knowledge. I'm sure there are subs I had not yet discovered, but a lot of the information they collected over the years may be gone. I hope those communities will find their way to Lemmy and rebuild.

FWIW, selfhosted does have a sort of "best of" list on GitHub at: https://github.com/awesome-selfhosted/awesome-selfhosted

r/oldhagfashion was a really fun one!

A bunch.

r/guineapigs - it was very helpful for new pig owners, and a great guinea pig fix when you're at work.

r/disney* - for a Disney parks nutcase like myself, the various Disney park related subreddits helped me get over the time between visits.

r/bestofredditorupdates - I get frustrated reading posts and not having any idea of how things ended up, but boru allowed me to indulge my interest in others' stories without getting frustrated by the lack of closure.

The list goes on and on.
