It’s nearly Black Friday, and we’re gearing up with a podcast about shopping, of course. This week on Why’d You Push That Button, Vox’s Kaitlyn Tiffany and The Verge's Ashley Carman discuss Instagram shopping: why do we buy stuff? They chat with Verge editor-in-chief Nilay Patel about all of the horrible gadgets he’s bought, as well as Vox reporter Rebecca Jennings about how the Instagram algorithm learns what we love and then targets us with it. Then they talk to Choosy, an Instagram-made company that uses software to figure out the hottest clothing trends to beat other brands to market. It’s wild, truly. And finally, they take every question we’ve ever had to Layla Amjadi, a product manager for Instagram Shopping, who explains the shopping product to us and how Instagram is building a “personalized mall” for everyone.
