I don't mean the usage of Apollo in particular, but my understanding from what I've read is that according to some metrics, almost 50% of Reddit have gone dark, partly in support of Apollo. It's already the unofficial alternative to Reddit, except also kind of being Reddit at the same time.

Correction: I did a quick check, and around 40% went dark according to this source, so not quite the 'almost 50%' that I proclaimed: https://twitter.com/aakashg0/status/1668107416490192897

Ah, that makes more sense. 40% going dark is actually way higher than I would have thought.

It also depends on how you interpret it. 22% of submissions, 38% of comments, 48% of authors, 43% of karma went dark.
