@cyclohexane@lemmy.ml I don’t think there is one right answer to this. IMO - anyone can start an instance for whatever reason they want, which could be to have a topic specific instance.
This may have an advantage. For example of someone wanted to start a gaming instance of could bring all the existing forms into one place, and then add a bunch that aren’t on the other instances. This could make for a convenient one-stop location for gamers to find all the topics they are interested in.
Of course nothing is stopping a use from subscribing from a different instance of they so choose.
@maegul@lemmy.ml I am wondering if communities can be private / approved users only… I didn’t see that in the docs.
