To chime in on the user creation thing:
I think it’s a natural part of decentralization that it’s harder for a single instance to get big enough to be the “go-to” for general users.
Having said that, I also think this will naturally happen over time. As long as the mechanical aspects of sign up are simple, it’s just a matter of users of a given instance to promote their instance.
World events also always play a role in encouraging a move to freer waters. Look at what happened with Mastodon and Bluesky (though Bluesky imo is just a big snooze button on a blaring alarm)
Strongly second this.
