From the second and third links (both blog posts rather than Twitter), only 1 out of 250+ submissions was from a woman, so the latter. Presumably a similar situation occurred in 2018, as there was a single female speaker out of the 39-person lineup.

Mark didn't cite a source for this, which is what I was looking for in the Twitter thread.

Oh, that's a good point. It might be sourced from crell's post: "According to them, they had only a single woman submit a session proposal this year...", which was from conversations with the organizers, so potentially nonverifiable.

You could probably check Mark's other claim more easily: "...the line-up last year was almost all male as well, just one woman out of 39 speakers."
