Traditional social platforms centralize control of community spaces—the platform owns your group, your members, and your data. On ATProto, ownership, governance, and moderation become explicit design decisions. This talk explores building shared resources on a decentralized protocol—from data synchronization to governance models—drawing from real experience building community features and examples from other ATProto apps.
