Since Elon Musk bought Twitter, over a million people (including Kai and Kimberly) have joined Mastodon, a decentralized social media network. On the show today, Robert Gehl, professor of communications and media studies at York University in Toronto, explains the ins and outs of Mastodon and decentralized social media and what it means for our public discourse. In the News Fix, we’ll talk about why mortgage rates are so darn high (it’s not all because of rising interest rates) and the future of self-driving cars — don’t plan to take your hands off the wheel anytime soon. Later, we’ll hear from a listener about what it takes to run for a local school board in Wisconsin. Plus, the eBay hack you didn’t know you needed. Here’s everything we talked about today: “What Is Mastodon and Why Are People Leaving Twitter for It?” from The New York Times “Mastodon Mobs and Mastodon Mods: Dealing with Outside Groups Pressuring Instance Administrators” from Code Sections Kai’s Mastodon handle: @kairyssdal@mastodon.world Kimberly’s Mastodon handle: @kimberlyadams@mastodon.online You can also find Kimberly on Tribel and Cohost “What Riding in a Self-Driving Tesla Tells Us About the Future of Autonomy” from The New York Times “Mortgage Rates Are High Because Nobody Is Buying Mortgages” from The Wall Street Journal We want to hear from you.
