If you want the fediverse to grow, tell your friends.
@Gargron: and do not propose through your official app (since it is predominantly used by newcomers) to sign up on just one server. Just tell your designers to make the better UX when selecting an instance. Use less technical language – e.g. “communities” instead of “instances” and, most importantly, revert the change centralising the most of the Fediverse in just one place. Thank you.
