@feditips I see a lot of people think this is a good thing. And that users will start there and then move away.
Have you met people?! People don't post their contents on a server, just so they leave it behind and go to another one.
Not to mention saying "pick my own server" make user think its for server admins/owners.

What if after a while the app become exclusively for mastodon.social? Is that ok too? what of mastodon.social become popular and then unfederated?
