And what about on the Democratic side?
Hammer, meet nail. It wasn't just the Trump side that was "misinformed" by Facebook; Clinton's supporters were equally in a bubble. "Fake" news did not impact only one side; it touched every single candidate. It was near propaganda levels, especially in the final week. Ad hominem was the normal response of the Clinton side; why rebut the argument when it's easier to attack the speaker. Straw man was the normal response of the Trump side; why respond to the actual argument when you can misrepresent it and have a slam-dunk rebuttal.
Maybe it's time for Facebook to realize that all their "algorithms" will be exploitable, and they should just go back to a perfect, unaltered timeline of everything a user is following. At least that way we can say it's the people choosing to be misinformed and not just a side-effect of an algorithmic choice.
