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 like the jerboa app on mobile but I dislike the desktop site layout. I've used Shine for Reddit for years for the grid layout. I'm hoping someone will eventually release custom layouts to make use of all the space on desktop. The content is about the same after subscribing to lots of communities.
There's some work going on currently to allow the previous Reddit third party apps to connect to Lemmy instead of Reddit. This should allow you to use Shine for Lemmy in the near future.
