I like the way Voyager does it:

DeltaChat also has a very easy onboarding process: you just put your name, and that’s it. The app creates the password in the background and allows you to switch servers easily. That really helps with onboarding new joiners.
Piefed.zip could be a nice default choice. If there are others you see, feel free to suggest.


The problem with your suggestion is that it creates centralization. See Mastodon.social, matrix.org, etc.
The solution, I have posted before, is to ask instances to be opted into a directory, and then present the user with a random suggestion from that list. There should be some basic criteria like uptime and a proper set of rules laid out of course.
Lemmy.ml isn’t the largest Lemmy instance
Piefed.social will probably go the same way once rimu decides to shut down the registrations to keep hardware costs manageable.
Your suggestion would be doable if there was another long established, up-to-date , generalist, non-flagship Piefed instance, but as of now I only know Piefed.zip
Piefed.ca is Canadian focused
Blahaj is queer focused
Piefed.world is vastly outdated
Anarchist.nexus is, well, anarchist
It’s also not a default instance in any apps that I’m aware of.
As it says in OP, none of that matters.
Isn’t Lemmy.ml the default in Jerboa?
I’m not @ada@piefed.blahaj.zone , but I’m quite sure they prefer to avoid waves of new joiners from Reddit signing up on their instance without knowing it’s a queer safe space
We have an application process. If they don’t show recognition of the fact it’s a queer safe space, they don’t get approved. We’ve also got a matrix bot to help trusted users approve signups, so we can handle volume ok as well!
