Since this is getting some traction, I'll append with two additional thoughts:
I actually *do* think news orgs should spin up an instance for themselves, because [email protected] looks goofy, but reporters should set up where they want.
And "where they want" shouldn't probably all be on the same server bc that becomes a real tempting honeypot for defederation battles.
All superexcellent points.
One thing I didn't realize at first is that you can be on many instances using the same email address. How does this affect your position, if at all?
100% agree there is huge value in splitting up the cost, time and energy required for moderation among many thousands of instances. Maybe this is a dimension of social life that should stay on a human scale, and never be automated.
Many, maybe most journalists seem to maintain alts for different things already. It might be analogous to email, where you maintain a more polite, professional one, and one for swearing like a costermonger.
I understand many in Mastodonia are on different instances specific to their hobbies &c (I've been on the same David Foster Wallace literature BBS since 2002 !! shoutout to @mattbucher )
