Some notes on social media – Kevin Drum:
The internet in general makes smart people smarter and dumb people dumber. This is easily explicable: the internet has a tremendous amount of useful information, but it's not easy to access. Smart people can figure out how to do it, and they have the background to figure out which information is reliable and which isn't. Dumb people can do neither, and often end up gathering information that ranges from merely flawed to flat-out conspiracy nonsense.
