The Crazy Internet
This 2 year old Reddit post came up on HN recently: Most of What You Read on the Internet is Written by Insane People.
The argument is that the vast majority of content consumed on the internet is generated by a very small number of very strange people:
If you read reviews on Amazon, you're mostly reading reviews written by people like Grady Harp. If you read Wikipedia, you're mostly reading articles written by people like Justin Knapp. If you watch Twitch streamers, you're mostly watching people like Tyler Blevins. And if you read YouTube comments, you're mostly reading comments written by people like Justin Young. If you consume any content on the Internet, you're mostly consuming content created by people who for some reason spend most of their time and energy creating content on the Internet. And those people clearly differ from the general population in important ways.
