Tommy Shane writes: “When it comes to data voids, a distinction is usually drawn between search engines and social media platforms. Whereas the primary interface of search engines is the search bar, the primary interface of social media platforms is the feed: algorithmic encounters with posts based on general interest, not a specific question you’re searching to answer. It’s therefore easy to miss the fact that data voids exist here, too: Even though search isn’t the primary interface, it’s still a major feature. And with billions of users, they may be creating major social vulnerabilities.”
