I run a few groups, like @fediversenews@venera.social, mostly on Friendica. It's okay, but Friendica resembles Facebook Groups more than Reddit. I also like the moderation options that Lemmy has.
Currently, I'm testing jerboa, which is an Android client for Lemmy. It's in alpha, has a few hiccups, but it's coming along nicely.
Personally, I hope the #RedditMigration spurs adoption of more Fediverse server software. And I hope Mastodon users continue to interact with Lemmy and Kbin.
All that said, as a mod of a Reddit community (r/Sizz) I somewhat regret giving Reddit all that content. They have nerve charging so much for API access!
Hopefully, we can build a better version of social media that focuses on protocols, not platforms.
I actually just joined today and this is my second ever comment. It wasn't too hard to get setup, given I hadn't been on any fediverse until now. I have to say I like how well the instances link together too, at least from what I have seen so far.
I am using Jerboa at the moment and while it is kind of basic it seems faster compared to Reddit Sync or the official reddit app. This is a very good sign as I have had issues with both offical reddit and sync in the past including a fair amount of crashes. I might have to look for a desktop app soon and at some other fediverse types (don't know the terminology), I know there is one for videos for instance.
I am kind of interested to see an instance like this. I am a member of r/Autism_Pride and some similar subreddits so this seems like somewhere I could spend some time.
p.s. Is there any drug or harm reduction communities I should now about? How about fountain pens or baking bread? Random I know but thought it was worth an ask.
In response to your postscript: You can search here for other communities: https://browse.feddit.de and there may be other search, please let me know if you find them. That one is a bit slow to update. I used that to determine that there was no community yet for a topic. So I tried to get a feel for which lemmy might be best for it and created it there. The one I created was Trader Joe's Unofficial You can see I even added a note in the description about it being my first and trying to add a better/more mod.
TL;DR See if your community interest already exists anywhere, and if not, go create it!
Thanks I have now found some of them at least. The interface for joining communities outside your home instance is kind of iffy. Having some issues using Jerboa and lemmy web in general compared to Sync and reddit website. I imagine the interface will improve over time, at least I hope so.
