For example [email protected] lists some sister communities. Are sister communities just communities with related topics? Also some communities have partner communities, does this refer to the same thing?
I guess the mods are friends?
Generally, yeah, just related topics. But there might also be mods that mod both communities.
I don’t think there’s any official distinction but what seemed to be an informal convention I noticed on Reddit was that sister communities were related topics (probably with some coordination/agreement among the communities’ mods) whereas partner communities tended to be related topics that had the same mod(s). Usually the latter might be something where any individual community would be less active so it would be easier for someone to moderate multiple communities.
For an example using music styles, maybe c/ClassicRock might list c/ClassicPunk, c/PsychedelicRock, and c/Prog as sister communities. If someone modded c/PinkFloyd, c/TheWho, and c/DeepPurple they might be listed as partner communities.
If someone modded c/PinkFloyd, c/TheWho, and c/DeepPurple they might be listed as partner communities.
That’s a lot of administration to do when a mod stops or a mod is added.
On the lemmynsfw instance, are they referred to as step-sister communities?
