MBin has embraced C4 and has got no single maintainer nor BDfL. It is a fork of /kbin (RIP), whose author (a Pole), Ernest, nobody had a problem with.

Another Polish creation, Prismo, is technically older than /kbin, or even Lemmy, and strikes back! Prismo is more of a Hacker News/Lobste.rs clone than Reddit one (despite less minimalistic looks), and got rid of magazines/communities, preferring to maintain smaller, topical instances, with hashtags being main tool to filter posts by topic. Prismo’s federation is under work: it works mainly with Mastodon (and maybe other microblogging) and MBin.
