We're making progress integrating Threads into the fediverse and launching a beta in a few countries that lets people choose to federate their posts. If you see this and turn it on from your profile, you'll see likes from federated platforms appear on your posts here.
@david1 no. Only "likes" will federate for now. It's a slow rollout. Eventually they will be able to see our replies, but according to Meta, that'll be one of the last things. Everything that benefits them will come first (Us seeing their posts, being able to follow and reply but not the other way around yet)
