The article explores the concept of a social filesystem, contrasting it with traditional file systems tied to personal computing. Files represent individual creations and provide a sense of ownership, allowing users to control their data. The author highlights how various apps, like Instagram and TikTok, currently operate with isolated data silos, lacking the file-like structure that would enable users to manage their digital identities more effectively. The idea is to treat social app interactions—like posts and follows—as files within a unified digital folder, or "everything folder," where all user-created content resides. This approach would fundamentally change how social apps function. Instead of each app independently storing data, they would react to changes in the user's folder. For instance, deleting a follow from Instagram would correspond to removing an "Instagram follow" file from the folder. The article introduces the AT protocol, currently in use by apps like Bluesky and Leaflet, which allows for this separation of data ownership from app control. The concept hinges on treating social interactions as "records," structured in JSON format, where essential information is stored while extraneous data—like user identity details—is kept elsewhere. The author emphasizes the importance of maintaining a clear boundary between user-generated content and derived metrics, such as likes or replies, which belong to the app rather than the user. This distinction helps clarify what data should live in the social filesystem and ensures user ownership remains intact. Ultimately, the vision is for a distributed social filesystem that empowers users by allowing them to move their data freely across different apps without losing ownership or functionality.
