There used to be a Kbin instance called feddit.online, which was shut down. @Jerry@hear-me.social just announced on Mastodon, that he brought feddit.online back to life, this time using PieFed. PieFed is a pretty neat alternative to Lemmy and Kbin/Mbin, created by @rimu@piefed.social and of course fully free and open source on Codeberg: codeberg.org/rimu/pyfedi
It has some cool features like “Topics”, which are basically groups of multiple communities that you can view all at once (similar to these Lemmy feature requests: github.com/LemmyNet/lemmy/issues/3071 github.com/LemmyNet/lemmy-ui/issues/1113).
