r/backcountry great resource for back country skiing and generally a good place to find awesome photos, trip reports, articles, and discussion. I created the community here but none of my skiing friends use social media.

There needs to be a comedy podcast aggregate community. Cumtown/The Adam Friedland Show, Matt and Shane's Secret Podcast, YMH, Bad Friends, Rogan, MMP, TFATK (homeless cats only), etc, etc...

I'm going to miss all the weird niche subreddits I was a part of that will probably never show up here in force because there's just not enough people on Lemmy to begin the formation of such niche subreddits. The amount of users interested in those things on Lemmy will be proportionally smaller compared to the number on Reddit, and so it will make it just that much harder to have flourishing and active communities around those things.

Firefox. AndroidGaming, Android, Windows11,Microsoft, Chrome, SmartLauncher.... lots of various speific support communities. Also valuable ones like AskDocs, AskElectricians, etc. Reddit is a really good way to find advice from people that know what they're doing (of course you have to be careful).

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.

SummonerSchool and CompetitiveTFT, I know there are discords but I don't like its format.

Linux_Gaming, PCMR, EscapeFromTarkov, NobaraProject, My city's sub.

Leafs. It's either that or Twitter, which I will certainly not use.

Luckily there's a Sports bot on Mastodon that duplicates Twitter posts from NHL and Leafs accounts. Will be good enough for me.

The various graphics programming subreddits. Weren't super active but every now and again there were some mind-blowing posts.

/r/aoe2 was one of my favorites. I hope plenty of users decide to make the switch.

r/tooktoomuch

I liked r/whatisthis and the other subs for identifying objects and places. I rarely knew what anything was and never posted, but I learned a lot about random items!

Mostly joke subreddits like r/VXJunkies and r/badfoodporn, but also game dev oriented stuff like r/Godot, r/PixelArt, and r/INAT

Biggest ones will probably be r/bouldering and r/climbharder.

The tech related ones will be more likely to have big replacements, but bouldering is pretty niche, so I'm not sure about that one.

Just added, I will post some stuff the next few days. Hope to make it active (: c/fuckcars

artisanvideos. I love a good japanese watch maker making a wooden cabinet in a rainforest with rocks as tools.

I'm gonna miss r/SubSimGPT2 and it's meta subreddit so much
