They are all available on every instance. It's not different than having five communities for the same subject on Reddit. It's worse here right now because so few communities have managed to "clear their orbit" yet, but it will get better.

But, that's not relevant to communities. You can kill a community by technical means, but technical means cannot create one; it's necessary but not sufficient, and not even the hard part.
Most people are still on fucking FACEBOOK. They are willing to put up with almost unlimited bullshittery for the sake of their sense of community. Building a better mousetrap won't work, and building a vaguely equivalent mousetrap won't even move the needle.
Lemmy is Reddit 10 years ago
I mean it's not THAT good, but it's sure better than Reddit today.
"Reddit is awful. How do we move that here?"
Most people don't change unless they have to, and rarely even then. You'd have to make it so that they can't visit Reddit anymore.
Even on reddit itself, you can't get people to move from a sick community with hostile moderation to the preferred community. /r/Canada got taken over by /r/metacanada what feels like decades ago, and they turned it into a post modern bigoted classist hellhole, but it still ranks far above the "real" Canadian sub /r/OnGaurdForThee.
Maybe better not to compete with existing communities. Develop some anchor communities on Lemmy that are doing their own thing on topics that aren't well served on Reddit.
...therefor no one ever has?
Far, far more likely to actually die.
Whenever I see a pepe, I assume it's someone who at least doesn't mind being confused for a terrible fucking person.
Just perfectly on-brand.
Utter non sequitur. This is something someone says to bulwark their worldview to themselves, not to convince others of the merits of their view. You're just proving my point.
The lies we tell ourselves are not convincing to others.
If the only thing I know about someone is that they are on Twitch, I'm probably not motivated to learn a second thing about them. One can say Twitch > 4chan > Stormfront, but it's a pretty shallow gradient.
