So which one is actually official one? I can’t describe what “official” mean here, maybe the one that actually came from reddit or the one with more subsscribers or one with more activity ?
Also Why there are multiple copies of same community in different instances? Isn’t the whole point of lemmy is that it is federated?
Yeah, it’s federated, meaning you can subscribe to each of them and post to whichever one you fancy. If you want to post to multiple, it’s a good idea to use the cross-post feature.
Having only one singular official community would be rather bad, as then the respective server owners and moderators would have central control like on Reddit.
