As internet use became common, communities formed in different ways. Early examples would include internet forums, or message boards. In the early 2000s a message board called 4chan was created that was anonymous by design. And posts made to it, and replies, were inherently temporary. While 4chan had message boards for all sorts of topics its anonymity combined with posts that would eventually disappear led to the emergence of an online culture that would seem strange and even extreme to many people who didn’t spend time there. Our guest grew up immersed in this online culture, and is now a researcher of it, so we thought he’d be a good person to help us understand this world a bit better as it seems to increasingly enter into mainstream culture, from media to public discourse, and the polarization it contains.
