I think any non-regional and non-special TLD is fine. Some have rules associated. I thought .movie had special rules about only lasting for a specific amount of time but it looks like I may have been wrong (not sure where I got the idea and I can't find anything to back that up). .us you have to be a US citizen for. .dev has the "rule" that it is HTTPS only because *.dev is in the HSTS always-on list by default but that's not related to the domain itself.
Even better, join a smaller one to spread out and make use of the federated nature. Right now imagine lemmy.ml and lemmy.world for whatever reason go down. Basically whole Lemmy is kinda fucked because it's extremely centralized, even though decentralization is one of the points of Lemmy.
We need a better way to advertise what servers to direct people to. Would be nice to circle through a big list of instances to evenly direct new users to
It’s hard to make anything “official” on the fediverse as things are distributed. Who makes the “official” determination for Lemmy? The biggest instances? The devs? Do we hold a vote across instances?
People couldn't care less if it's centralized or not. People come for the community, not the tech behind it. Also people are lazy, they will use the easiest thing that comes up. Why should one go to another instance, if the one they are right now works great?
I am not saying that this system is bad. I am just saying that people will always take the easiest option there is.
Well, I'm not blaming the people, really. This is a communication issue, it should be well advertised to do it "correctly" and it should actually be the easiest option.
How I see it is that every decentralized system with people is going to form some sort of centralization unless you actively fight against it.
In Lemmy's case, new people will check what are the biggest communities and go there, and since there are more people there, it attract even more people. More people, more communities in that instance.
