Today we’re making signing up on Mastodon easier than ever before. We understand that deciding which Mastodon service provider to kick off your experience with can be confusing. We know this is a completely new concept for many people, since traditionally the platform and the service provider are one and the same. This choice is what makes Mastodon different from existing social networks, but it also presents a unique onboarding challenge.
Seems like it is only new users that sign up on JoinMastodon. Seems you can go to any of the servers QOTO, C.IM, Fosstodon, Infosec., etc. and still sign up directly.
Yes of course, he can’t control that. And he wouldn’t want to change that I hope ^^
