@atomicpoet okay maybe I’m an outlier but most of my family would absolutely be confused by it, at least until after they’re onboarded and familiarized. They use email because they don’t have to think about it and it’s trivial to find a provider.
I guess the current policy with mostodon does hurt discoverability even more but I think making it easier to find those other services and communities would make a bigger difference than changing the signup flow specifically.
