>Twitter seems to have evolved more into just really stressed out people yelling at public officials
these are both good points, but i think that there should be a bit of context: by and large in the US, public officials are performing unexpectedly, astoundingly, and utterly unforgivably poorly in their responses to the coronavirus.
it's the correct response to be anxious about the wholesale failure of public and private institutions, and it's the correct response to be livid about it and to channel anger towards those who are letting the country down in its greatest time of need.
it's fashionable to say that disconnecting is important for your mental health. it isn't that the idea of disconnecting for the sake of mental health is in any way incorrect. but democracies function via the will of the public being reflected in the actions of individuals and institutions. if public officials don't have people giving them an earful, they will in all likelihood continue to act in a way which harms the public.
in other words: without the endless hammering of the anxious and unstable twitterati and those like them, the public health response to the coronavirus in the US would likely be even worse than the near worst-case response that we're seeing. it's bad for the people doing it, but it's part of the democratic process at this point.
