Hi django@social.coop! The post didn't make it over to the correct category because I don't think you actually mentioned the group.
Anyhow, the three "fediverse" categories are identically named categories from three separate instances: piefed.social, lemmy.ml, and lemmy.world
They each have various amounts of traction and neither has really won over the others (despite what the inhabitants of each community would like to tell you).
I currently do not have the capability of "nicknaming" a remote category, so they remain identically named, for now. :sweat:
