The deep irony is that some of the original contributors to Birdwatch were working on this stuff at Facebook before being blocked for various reasons and leaving to work at Twitter.

To steelman this a bit, early versions of Birdwatch had problems with unsourced notes and speed of note display. There’s a bunch of research that shows that 1st impressions of info tend to dominate, so speed matters a lot.

In practice FB’s program was poorly resourced and overly complex so I’m not sure it ever achieved its theoretically lower latency.
