Intersting that Joe Biden is now available via Activity Pub:

Looks like Threads is indeed federating with everybody:
https://indiehackers.social/@potus@threads.net
So you could make your own instance and read everything in exactly the UI you want? Customize sorting and discovery via your own algorithms?
Is that the open web 2.0 we have been waiting for?
PS: Looks like you can't link to external accounts on a typical Mastodon instance the way I did. When you search for "potus@threads.net" and click on the result it works.
