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.
It should be noted that while Rust is rarely used, some very big players are pushing it. E.g. last year Microsoft Azure’s CEO tweeted that “it’s time to halt starting any new projects in C/C++ and use Rust for those scenarios where a non-GC language is required”, Windows contains some Rust code now and the Linux kernel also supports Rust in addition to C since December.
