This is part of a larger debate that the world's been having for the last seven years or so about whether social media should be filtered, moderated. People have tried to do such things and try to have committees and advisory boards to assess accuracy of scientific medical fill in the blank information on Twitter. But science does not seem to work that way, or at least it didn't in the past. And I think your point about, say, alchemy or other efforts, they failed and the marketplace of ideas, judge them harshly.
