Was at an event recently where they have 2 male and 2 female speakers every year. This year it was 2 male, a TW and a woman. The event isn't important, it's not some great career thing where women are underrepresented so I'm not really bothered, but why does it always have to be a TW replacing a woman? That's more my problem, that I bet it never occurred to the organisers to have 2 female, 1 TW and 1 male. It never seems to occur to anybody.
