For me its having a single instance that indexes all the communites to which all other instances can then pull that information from so when I go searching for communities the I’ll have access to every single one with needing to post the entire URL in the search bar
Yeah my #1 issue is how hard it is to find communities to follow. I think it’s why so many communities are just started on lemmy.ml since it has the best chance to get users on there or Beehaw.
