Threads has entered the fediverse (via) Threads users with public profiles in certain countries can now turn on a setting which makes their posts available in the fediverse—so users of ActivityPub systems such as Mastodon can follow their accounts to subscribe to their posts.

It’s only a partial integration at the moment: Threads users can’t themselves follow accounts from other providers yet, and their notifications will show them likes but not boosts or replies: “For now, people who want to see replies on their posts on other fediverse servers will have to visit those servers directly.”

Depending on how you count, Mastodon has around 9m user accounts of which 1m are active. Threads claims more than 130m active monthly users. The Threads team are developing these features cautiously which is reassuring to see—a clumsy or thoughtless integration could cause all sorts of damage just from the sheer scale of their service. # 22nd March 2024, 8:15 pm

Meta/Threads Interoperating in the Fediverse Data Dialogue Meeting yesterday. Johannes Ernst reports from a recent meeting hosted by Meta aimed at bringing together staff from Meta’s Threads social media platform with representatives from the Fediverse.

Meta have previously announced an intention for Threads to join the Fediverse. It sounds like they’re being extremely thoughtful about how to go about this.

Two points that stood out for me:

“Rolling out a large node – like Threads will be – in a complex, distributed system that’s as decentralized and heterogeneous as the Fediverse is not something anybody really has done before.”

And:

“When we think of privacy risks when Meta connects to the Fediverse, we usually think of what happens to data that moves from today’s Fediverse into Meta. I didn’t realize the opposite is also quite a challenge (personal data posted to Threads, making its way into the Fediverse) for an organization as heavily monitored by regulators around the world as is Meta.” # 12th December 2023, 1:05 am
