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.
Indeed - the government should go where the people are, not force them to use some dedicated governmental outlet. Of course, they should be using as many outlets as possible, including their own (for verification if nothing else). Just as announcements go to every major news outlet, they should use as many as possible today. And many do.
