Does anyone know if it's normal to keep the title/content of talks TBD until that soon before the talk? That stood out as odd to me.
She has a few talks on slightly edgy topics which she gives at different venues. The "hackers and suicide" one from CCC was probably more interesting, but that was just delivered 2 months ago to a largely overlapping audience.
I'd never put a Bond Girl in my talk (I might have at one point, but now I'm convinced it's slightly offensive); there's no reason. A Lena photo for an image processing talk, maybe, because that's essentially the standard.
However, I'd be fine with a talk about sex, drugs, rape, suicide, etc., if it served a purpose. It has to be in the right venue, and I think BSides actually is a good venue for a lot of those topics (or CCC, or HAL/HIP/etc., or parts of Defcon, or Hope, but not RSA). It should be disclosed up front, and ideally way in advance.
