I have a long commute in and out of a large city. Since I spend so much time on the road, I always try to get the details of Amber Alert notifications to be on the lookout for vehicles used in abductions. I guess I can't do that anymore since Twitter requires an account to see Amber Alerts. Hopefully my state finds another platform to post them.
I didn't even consider the fact that the fediverse offers us the ability to start having publicly owned social media and government-run instances for direct communication.
That could be very interesting...
Various EU agencies have already set up their own Mastodon instances and are pretty active in the fediverse.
