Threads Introduces Limited Ability to Follow Fediverse Accounts

Meta's Threads app takes a step toward interoperability by allowing users to follow Mastodon and other fediverse accounts, though significant limitations remain.

Threads users can now follow fediverse accounts, such as those on Mastodon, directly within the app if certain conditions are met.
To follow a fediverse account, users must see interactions like likes, follows, or replies on a federated Threads profile, or find linkified fediverse usernames in posts.
Fediverse posts do not appear in Threads feeds, and users cannot reply to posts originating from other fediverse servers yet.
Notifications for new posts by followed fediverse accounts are available, but full interoperability remains a work in progress.
Meta continues to develop Threads' integration with the fediverse, aiming for a safe and diverse interoperable ecosystem powered by the ActivityPub protocol.
