I really like what @macstories@mastodon.macstories.net have done by setting up their own server.
It’s a much clearer way of showing that an account is official than a blue tick (or, for that matter, a green URL in a profile).
It’s also means you to browse through all their posts by looking at their public timeline: https://mastodon.macstories.net/public/local (is there a way to follow a whole instance?)
Plus the usernames look cool.
I hope other publishers and organisations do the same.
