> Social media has made it wildly easy and incredibly cheap to propagate any misinformation. Head over 4chan and you'll see a factory line of ideas being thrown at the wall to see what sticks - which is then further spread across social media.

4chan has always been like this. Pre-2007 it was basically the boiler room of the internet. You could find memes before they hit mainstream along with all the shitty ones that didn't make the cut.

I'm sure this natural filtering was disrupted when we brought millions of users online for the first time and convinced them that social media is the internet.
