An interesting list, though I feel it omits the elephant in the room:<p>In becoming the largest single media platform ever, operating at fantastic scope, speed, and with the ability to selectively filter and focus attention, today's social media platform monopolies have also become the heart of epistemic warfare.<p>This isn't simply a room with a few friends, it is a substantial fraction of <i>everyone</i> (2--3 <i>billion-with-a-B</i> monthly average users) on the same place at more or less the same time. The Facebook logo is among the most reproduced and seen icons anywhere, rivaling the Cross, the Crescent, the Dollar, and the Yuan.<p>As my friend Wooze pointed out a few years ago:<p><i>Our present epistemic systems are undergoing kind of the same shock that the online community underwent when transitioning from BBSs and Usenet to the commercial web to social media.</i><p><i>We were used to a very high content-to-BS ratio because it took a certain amount of intelligence and intense domain-interest for people to be there in the first place -- and we've now transitioned to a situation where many people are there more or less accidentally and (the worst part), because of a high percentage of the population being present, there is now substantial power to be had by influencing the discussions that take place.</i><p><a href="https://old.reddit.com/r/dredmorbius/comments/5wg0hp/when_epistemic_systems_gain_social_and_political/" rel="nofollow">https://old.reddit.com/r/dredmorbius/comments/5wg0hp/when_ep...</a><p>This is far more the case than any lunchroom, cafe, street corner, agora, or meeting hall.<p><i>Assembled audiences have value, and that value is in manipulating them.</i> Usually not in their own interest. And usually by multiple different third parties, each with its own motives.<p><i>That</i> resulting dissonance is itself mind-warping in is effects. It also has profoundly dislocating and disruptive effects, in the worst possible way, on entire nations and cultures.<p>A related question is "What makes an information regime oppressive vs. liberalising?"<p><a href="https://old.reddit.com/r/dredmorbius/comments/6b32jo/what_makes_an_information_regime_oppressive_vs/" rel="nofollow">https://old.reddit.com/r/dredmorbius/comments/6b32jo/what_ma...</a>
