Which is good because I almost skipped the video for that reason.
YouTube star CGP Grey explains in an extended metaphor how ideas spread on the internet and why certain ones spread faster and with greater depth than others. He calls this concept a "thought germ."
In the internet content business, there is one essential question: what gets traffic? More clicks mean more money. Predicting what will go viral is an incredibly difficult task that combines intuition and statistics. The statistics that CGP Grey points out say something important: anger gets traffic.
Angry thoughts are a type of thought germ that can reach across huge audiences and divide them. They split along different sides of a controversy. But those opposing thought germs are actually cooperative partners because they contribute to the spread of each other.

@cgpgrey I like this video because its a Rorschach test: What springs to mind first tells you more about yourself than the video itself
