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.
As anything it’d start with the techies, the platform becomes stable and tools are developed to make onboarding easier. My intention is to replace any communities that I can replace with Lemmy. We’ll see from there. The !selfhosted@lemmy.world community is already taking off (naturally), now I am kinda hoping !Eredivisie@feddit.nl and an OSRS (2007scape) community takes off.
