My government has been posting a lot of information (weather alerts, road works, etc.) on their own, dedicated Mastodon instance. They don't really advertise it, but it's good they have a platform to publish live information to in case the Americans continue to get weirder.
Some services have shut down their Mastodon presence because their social media team found too little interaction and they don't want to use simple forward bots that nobody responds to, unfortunately.
