Well they’ve finally done it — you can now follow Mastodon users from Threads (with some restrictions; see screenshot). Easiest way to test this is to search for your Threads account here, like the latest post, then check back on Threads. Follow your Mastodon self from there. Once this gets 100% functionality, I will hopefully be able to start pointing Threads users to my Mastodon profile.
Your account is not yet visible from Threads. If you follow @evanprodromou , then people there can find you (not just me). I think they aren't doing Webfinger search correctly, so people can't find you from Threads unless you start the process.
@ricmac It will be interesting to see how Threads ventures into the Fediverse. I have no Threads account, nor anticipate making one, so, I cannot really test things or see if, for example, my profile on my instance is accessible or not.
I wonder if Threads will ever really permit open, bi-directional federation with the Fediverse considering moderation concerns within a centralized platform such as their own. It could be that Meta only permits open federation with a few larger Mastodon instances and otherwise blocks out the wider Fediverse, either via purposeful intention or through ignorant naivety adopting Mastodon's #fediblock lists (either would deliver essentially the same end-result). @evan
