I’m a reddit refugee trying to figure this out. It seems to me like it’s a decent idea to break up countrol like this, but unfortunately there are some inherent problems that mean it might not work in the real world.
The biggest in my view is that communities are scoped to the instance they started in. You could have 2 different communities with the same niche and the same or similar name but different insurances and the subscriber numbers will be split across them. I think this is damaging to growth because it spreads active users.
Eventually if the niche grows one of the communities of the niche will be the biggest and most active. So generally users will consolidate around the instances with the most active communities thus making those instances have a lot of control and defeating the purpose of federation.
Is there something I’m missing here? Because currently I’m not convinced this can both grow and keep things decentralized.
Yeah, as big as Reddit’s namespace for subreddits was, Lemmy’s is another dimension bigger because you can have one community per name per instance. This feels daunting and possibly confusing at first. But honestly Reddit wasn’t much better. In fact, I think Lemmy’s approach solves certain issues that Reddit’s approach created, such as:
r/actual_subreddit u/PM_ME_YOUR_GANGLIA registers r/nerves, then neuron enthusiasts come in to talk about the latest in sensory meat, except u/PM_ME_YOUR_GANGLIA is a terrible person who runs the sub like a complete asshole. So u/teh_whizzz opens up r/actual_nerves or r/nerve_tissue or whatever and that becomes the actual place for nervous system affectionados to hang out…until the meme spam becomes excessive and then r/nerve_memes has to split off…you know what I’m talking about.
There’s no reason for that to happen on Lemmy, because if the mods at !nerves@lemmy.ml won’t quit dipping their infected foreskins in the punch bowl, someone can open !nerves@lemmy.world or !nerves@sh.itjust.works. Eventually most traffic will move to the “actual” one that isn’t run by skid marks. Newcomers who think “I wonder if there’s any communities about nerves” will use the search communities feature, then check out the most popular one.
In the big Reddit Exodus 6 months ago, a lot of people joined the platform, created various identical communities on various instances…most of which went on to gain no traffic whatsoever. Everyone searching for communities ended up going with The Popular One for whatever topic.
Or, even if there are simultaneous functioning communities, this means one of two things: folks will end up subscribed to both, maybe the mods maintain slightly different aesthetics or house rules so they’re both useful in different ways, or the same posts get made to both so you only need to be subscribed to one.
Then, what if the instance a popular community was on goes offline? This can, has, and will continue to happen. The community can coalesce again on a different instance and keep right on tranglin.
I just want to add here that users can adopt abandoned communities to give them a second chance. So if, in your example, the mods of !nerves@lemmy.world would rage quit and just squat on the name out of spite / indifference, then someone interested in cleaning up the mess can go to !support@lemmy.world and request to adopt the community. The admins can then decide to either directly transfer mod rights to the new user, or purge the community so another one can reopen it again, so there is technically no need to create additional communities in such a case.
In case of a direct transfer, no posts or comments get deleted either, so you won’t lose content that you would otherwise have to repost or crosspost to the “new default community”. ;)
On my home instance there was a call for mods for take over communities that had been created and apparently abandoned, both with and without content. “If no one steps up, we’ll just delete the ones without content and make the names available again for the future.”
In practice, it’s not much of a problem.
