Does that affect interaction? Perhaps this is a difference between platforms? When I signed up to PieFed, I chose some interests and it automatically subscribed me to various communities, some of which had the same name but different instances (for example five different communities named “Games”). I don’t know much about how community discovery works on any of these platforms to be honest.

Well, on Reddit people often do create new communities for the same topic because they don’t like the rules/culture/mods of the original one. So would you say that’s the same reason for choosing a different community on the Fediverse?

I’m not trying to make any argument either way, I’m just curious why people made the choices they did. For example, I saw someone from lemmy.world posted on programmer_humor@programming.dev even though programmerhumor@lemmy.world also exists. I’m wondering how they chose the first option over the second.
