Really interested to see how, or if, Threads impacts Mastodon. Encouraged that the Mastodon team are taking a measured approach to any federation discussion, and hope that other ActivityPub apps do.
No doubt anything with Facebook has to be scrutinised closely, but I feel these networks need to be resilient to for-profit organisations or bad actors coming along too, and there is an opportunity that scale brings.
