Adam Mosseri:
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 have no interest in interacting with Threads myself, but I suppose it’s good news for people who want to be on the fediverse but just can’t manage going without being able to follow @burgerking@threads.net or whatever.
