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.
16 year user of reddit here, just create the communities you miss. With the massive influx of users, they will fill up quickly. It only took 1 day after I created lemmy.world/c/psvr for people to start posting content there. It feels to me like it will only take a few weeks before we can have some semblance of parity to reddit content. And it feels much more like pre-digg migration reddit to me, which is very much a good thing. I think the golden years for lemmy will be coming quite soon.
