Twitter is taking an awfully long time to die, but its death is widely seen as inevitable.
Some people have already fled to other social media sites, e.g. Mastodon, or the newer Bluesky or Threads. I did too, to be fair.

POSSE is essentially a fancy new acronym for a very old idea - publish and syndicate content. The tools, like RSS and Atom, have been around for years. ActivityPub is really neat, but it’s an evolution of an existing concept.
