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.
You just shouldn’t start a community and expect others to post in it a lot 🤷 Most people are lurkers anyways, and the prolific posters are probably already busy with their own communities. So especially in the beginning, it is yours to carry, so chose a topic you are personally interested in and know enough about to regularly post and make good comments. People will come if the community is worth it, the specialisation doesn’t matter.
!eurographicnovels@lemm.ee has been kept active by @JohnnyEnzyme@lemm.ee and the other mod since the creation of the community 2 years ago, so I’m not sure people will come whatever the specialization of the community.
Oh rabbits-- you know something– I will always try to do my best, for BLAZE.
Also, that’s not what the post says. The post says to only fork a niche community once the more generic community sees a lot of content from that niche. It’s not opening a community and waiting for people to magically arrive.
Not easy for a single user to constantly posts content for weeks or even months and still almost nobody else is posting
