The content on all the communities seem different.
Why didn’t the “copycats” get the “this community name has already been taken” message?
It was bad enough at The Other Place finding one overlooked sub about one of your interests.
Now you have to find every single community in every single instance if you hope to talk about your topic?
I mean, look at this:
No Stupid Questions@lemmy.world
No Stupid Questions@kbin.social
No Stupid Questions@lemmy.ca
No Stupid Questions@mander.xyz
Because having communities with an identical name on different instances will fracture the community. Given the hallmarks of the fediverse this is practically intended, to my understanding, but it is bad for initial growth and coherence of posts. This happened on Reddit as well, of course it did, but the way instances are completely separate and communities can have the exact same name compounds the issue.
They’re different communities on different websites, though. Trying to force them all into one space is erasing all communities but one, just for the sake of having to see an @website.com address, or for pretending you’re not missing out on something when you ignore 99.9% of posts and comments that end up in the space.
1 million users discussing a topic spread out across 1000 communities of 1000 active users leads to more vibrant and meaningful discussions on that topic than having 1 million of them all crammed into one place, shouting and competing for slivers of attention. And no one will miss anything of deep value in the 999 other communities, because people will cross-post the good bits anyway.
