For today’s issue, we’re focusing on Reddit. If you are not a Redditor, you may wonder why on earth this website is important. For one thing, it’s the fifth most popular website in the country. For another, it has a significant impact on how information spreads online, especially when it comes to politics, especially since the 2016 election. When we wrote about fringe groups for The Masthead last fall, I asked Trevor Martin, a researcher who studies the internet, about how Reddit communities evolved over the course of the 2016 election, and what that suggests for our politics. Over the past few months, he’s been working on a data-driven answer to those questions, which we’re sharing with you today. Then you’ll hear from Srijan Kumar, another scholar who focuses on Reddit, about the tiny group of Reddit communities responsible for the vast majority of inter-group harassment on the site.
