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.
Enjoying it so far, thankfully I had already been using Mastodon for about 6 months so I've had time to get used to the quirks and discoverability issues that come with the Fediverse. I hope the learning curve doesn't turn off less tech savvy users.
One difference I'm struggling with is how to search past posts? I can find communities easy enough, but how do you search a specific issue that's covered in a post somewhere?
