Edited to add: Lol, this was originally about Threads not kicking off their fediverse tests yet, but it looks like literally within minutes of me writing this, those tests began. I guess check the edit history on this to see the info I posted originally, but as of now you can now look up @-mosseri@threads.net (minus the dash I put there) and see posts from that account, at least from Mastodon-style servers
