the concept of duplicate communities in general seems extremely based in reddit culture in general and seems antithetical to what makes the fediverse interesting- in reality theres no such thing as 'duplicate' communities, and having redundancy, competition and options is nothing but a good thing for user experience

communities with the same name across different instances are ultimately still different communities, regardless of how much overlap there is regarding content or users

needing one of them to 'win', or more importantly, needing all the others to 'lose' seems like arbitrary tribalism for no real reason other than mimicking the reddit experience

appreciate the duplicate communities for what they are or might become- slightly different flavours of the same base concept that you can pick based on which one you vibe with most

I don't even think it's a difference with Reddit. Reddit also has community duplication. Sure, maybe not as bad, but it's there. Compare /r/meirl to /r/me_irl. The only difference is that in Fediverse you'll see the same community name in different instances, but is it really that much more confusing than the meirl case?

There is, yes, a lack of discoverability for communities. Maybe we need a "recommend me a community" community. Like "I'm looking for a Spanish speaking science fiction community", and people can say "oh, yeah, try this one".

Other than that, the main advantage Reddit has in this area is that it has had a more or less stable population for a very long time, so which community wins out out of an initial set has already been resolved, while this is younger (yes, it's been around for a couple of years, but most people here haven't) and therefore that process is just starting to play out.

I have concerns that centralized activity will have the reddit problem - administration on those servers may not be ideal or quality could deteriorate over time.
