Facebook ads, Twitter bots, TikTok teens—over the last decade, social media has played an increasingly important role in our social and political discourse. This week, we continue our conversation with UVA Media Studies Professor Siva Vaidyanathan to discuss the way social media algorithms can unintentionally help organize radical groups and why social media platforms don’t bear the same liability for content as other publishers—namely, Section 230 of the Communications Decency Act. After that, journalist Brad Kutner takes us into a recent defamation suit in Virginia involving California Congressman Devin Nunes, Section 230, and a Twitter account for a fake cow.
