Mastodon provides a federated social networking experience, enabling users to join independent, community-governed servers (instances) that interoperate via the ActivityPub protocol. The primary web workflow involves selecting an instance, registering an account, and then engaging in short-form public or private messaging ("toots"), following users across the 'fediverse,' and participating in distributed discussions, offering a distinct alternative to centralized social platforms.
