Setting up a “verified” Mastodon instance would be a fun project for The Community Foundation for local nonprofits and maybe the Virginia Municipal League for local governments.
Meanwhile, countless government agencies also use the birdsite as a vehicle for messaging of all kinds. In situations where people want the vital news — such as forest fires, storms, etc. — Twitter has become one of the default places to check. They, too, can and should migrate to services like Mastodon. They should plan collaboratively to cut over to their own verified instances, in an orderly way that gives their constituents notice and time to get adjusted to the new system.
