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.
My guess is that redditers will want lemmy to be just like....reddit, but without the public-corp nonsense and with UI that is at minimum on-par with 3rd party apps people gravitate toward on reddit.
I'm totally new to this so I'm also figuring out my way around. The federated organization is confusing for sure, but not so much that people can't get it.
Some work could be done from a user focus... Simplify(including caring for duplicated hosts and communities), educate on lemmy's benefits, make searching for new communities seamless and less of a quest.
