@stevenray @anildash @whitehouse @tchambers I haven’t tested it but my understanding is that Threads users see some aggregated stats about Fediverse activity but I don’t think can see specific replies or boosts (they can see how many different servers interacted with a post but I don’t think they can see the replies.
However I hope this changes (and that threads users can follow fediverse accounts etc) but I have no unique knowledge if/when that will happen.
