Social media bubbles may threaten democracy
Social networks are just a mechanism for sharing stuff. Fake news could spread any which way, and has even in the pre-social-network-era.  Remember when "fake news" was spread in email chains? Or...you know...propaganda in general?Edit: that said, I think there exists a big problem in attempting to filter these items. How do we determine what is fake vs what simply goes against our preexisting (mis)conceptions?Edit 2: best course of action might be that a wide diversity of ideas gets a chance to be seen (i.e. show stuff outside of your bubble), rather than trying to artificially manipulate proliferation.
