Interesting that they mention their users being able to leave Threads and take their audiences with them which sounds like they want to support people being able to move to Mastodon, something many were worried they wouldn't do
But, you're @[email protected] and it works fine. It depends how you're searching. If your instance on Mastodon doesn't know anyone on Lemmy.one then you will need to put in the full path to find an account. But considering my Mastodon instance knows about Lemmy.one I can see your account.
Oh yes, my Mastodon accounts are able to follow and interact with my Lemmy account. I was referring to Meta's claims that Threads would federate. Apparently, it's not working yet.
