Back with newsgroups the general rule was to go from general to specific. You start with a general discussion group and when discussions about video games get annoying you create a games group. If then there are too many Baldur’s Gate discussions you create BG. If they are dominated by Baldur’s Gate 3 you create a Baldur’s Gate 3 group. If everyone is fawning over Withers you create a Withers group which of course will be flooded with discussion about the Withers’ tits mod, which shall get its own group.
Meaning you should create a group when demand is there and not the other way around.
Depends. Communities can create demand. Like !outofcontextcomics@lemmy.world .
It got launched by one poster, took off, and it’s awesome. It wouldn’t have fit into a more general comics community.
Indeed, but I feel in this case the topic is still broad enough that enough people saw the appeal and wanted to contribute
