Not just that, but the official app and website are openly telling people to just sign up on mastodon.social.
I get that they want to keep things as simple as possible for users who don't understand federation, but they could have recommended a server with a long track record that isn't quite as large.
And they didn't.
@feditips @bitflipped they could've even provided multiple servers and you get to one randomly when you sign up, but they did nothing.
