Just found out about this and thought it was neat. For those of you that don’t know, a Lemmy instance won’t automatically federate everything everywhere all at once. It’ll federate only what local users are subscribed to. So someone made a tool that will let you increase visibility of smaller communities that might not be synced to every instance.
Looks like it’s opt-in, and instances can avoid using it. Some do because it’s a lot of server cost for stuff they don’t care about.
I’ve created a few communities, and wondered why I was immediately getting ~30 subscribers, and this is probably why
I still think it will not explode bandwidth and storage, but I can’t argue because I don’t have any valid evidence :)
The reason I say this is that communities take up a few bytes in the database and if there is no activity (post/comment), they don’t use any bandwidth either.
However, I can’t say anything about the organic /all tab argument. It’s a matter of preference. Kind of funny one.
