The BBC's experiment with Mastodon is pathbreaking in English-language news -- a major organization setting up its own instance. They've really thought this through. Key language:

"We're using social.bbc as the domain, so you can be sure these accounts are genuinely from the BBC. And by linking to and from the BBC’s website, we have verified our identity on Mastodon."

@dangillmor @BBCRD I’d like to think American broadcasters will take the hint, but I know I’d be wrong. They will drag their feet for 5 more years. At least. If they do it at all.
@shoq News orgs in general, not just broadcasters... @BBCRD
@dangillmor @BBCRD Yes, agreed. I’m just hoping an icebreaker like this moves at least one sector of journalism to move even one herd. This makes me a bit more optimistic it can happen.
@shoq @dangillmor @BBCRD I'm hoping it will lay enough of a cowpath for others to follow, particularly around identity verification and moderation. Very interested to see if they start bringing individuals within the BBC in or stick to "channels".
