The Big Social score so far:
- Twitter: burning
- Reddit: detonated a bomb under itself
- Meta: rumored to join #ActivityPub with a new app
- YouTube: videos were always 2nd to "native" ones on the other networks, but they could trivially open an #ActivityPub firehose (and maintain their preroll ads while doing so)
- rest of Google: never found organic success and don't have a bet in the game apart from wanting to index everything

No predictions here, just stating the obvious. @fediverse
