What you're witnessing in real time is why "just creating your own subreddit" rarely worked. You can't compete with an overwhelming existing userbase being told to go to their alternative that they control, it doesn't matter what was first or better either.
Are the Reddit mods also mods in the Lemmy instance, If yes that might be the reason. Also feddit.de defederated not long ago for a while from Sh.itjustworks because of Moderation Problems.
Two of the reddit NCD mods are mods on the lemmy.world instance. None seem to be mods here. I guess that's why they're promoting that instance over this bigger (for now) one.
¯\_(ツ)_/¯ I tried to reach out to them over Lemmy two times in the last month and never heard back. I don't really have a problem making them mods if the community here wants.
Or all three. I can't get enough of the cold greasy gas station pizza that is NCD. There is one on kbin.social, one on lemmyworld and one here, my favorite. I migrate, grazing on dumpster sushi seasonally....
"There can only be one" isn't literal. Obviously there can be more than one otherwise why would I be asking which of 2 instances should we use.
But network effects will tend to grow one at the expense of the other and it's a feedback loop that will likely end up with one being dominant by far. I'm just speculating on which that will be.
Ok, consider matrix which is federated e2e chat. There are a few instances but the "dominant one" is matrix.org, the public test instance setup by the matrix devs. You probably do not want to use this one unless you absolutely have to. The reason being is that the instance is so large that chats take a while to load and sync and there can be some downtime as the servers are overloaded lots.
You can instead run your own little instance with no sign ups, just you, and still chat to everyone on matrix.org as well as the other federated matrix instances. Bonus, when matrix.org goes down, you can still chat with users on your instance and other federated matrix instances instead of waiting for matrix.org, your chosen, "dominant" instance to come back online.
This is a mental trap folks get into. Centralized services suck and are antithetical to the web's design.
Think of these federated instances like email and ask the same question: "which will be the dominant email service? Gmail? Fastmail? Aol? Protonmail?" The answer is you choose the one you want for the reasons you want, and don't sweat it because it will likely communicate across the rest of the internet (unless blocked by spam filters).
Things to consider in an instance:
do I like the end result of my handle (e.g. rarely@sh.itjust.works vs someone1235@lemmy.ml)?
does the instances values somewhat align with mine? I mean to say if you consider joining threads as your fediverse instance, you mind find less content or a worse interaction with content in general? If you join a right wing server as a leftist, you might find the only content you can access is content you don't want to see, as other instances have blocked that instance..
think they will be around for a while? Think again! All of lemmy instances are run by volunteers. If you don't mind instance hopping when one goes down, just pick one. Guessing which instance will have the resources to continue in years time isn't something you're going to get a good feel for years to come. Lemmy content isn't going to easily monetized meaning likely most instances will need to rely on donations in some form to pay the datacenters who literally keep the lights on.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !noncredibledefense@lemmy.world
