QR codes have been around for almost 30 years, but they’ve seen renewed interest during the pandemic. They’re convenient for customers, and they can help restaurant owners sell more. But they’re also a useful tool for collecting customers’ private data, and that’s raising red flags. Erin Woo (@erinkwoo) with the New York Times talks with Recode’s Adam Clark Estes about the privacy concerns behind QR codes.

We are sharing the first episode of Land of the Giants: The Facebook/ Meta Disruption. Long before Mark Zuckerberg renamed Facebook Meta and made an unprecedented pivot into the metaverse, he invented a feature that turned Facebook into a social network behemoth. The News Feed, which put your friends’ status updates onto your homepage, changed how we interact online. It was a strong statement of Zuckerberg’s values: that connecting and sharing at scale would be de-facto good for the world. It was also his first public controversy. Follow Land of the Giants to get new episodes every Wednesday.
