Second, threads posted by me and a few members of the Threads team will be available on other fediverse platforms like Mastodon starting this week. This test is a small but meaningful step towards making Threads interoperable with other apps using ActivityPub — we’re committed to doing this so that people can find community and engage with the content most relevant to them, no matter what app they use.
I see we’ve hit the first E: Embrace. I’m betting it’ll only be a few months until they’re Extending the protocol. Any wagers on how long until we hit Extinguish? 3 years maybe?
