>>Berisl+(OP)
For presenters to pad their CV. Source: that’s literally why I do it. Plus nothing like getting a LinkedIn-ready picture of yourself on stage in front of a ginormous screen with a headset looking all TED.
Edit: Or if you create a conference that will largely be attended by tech employees you can make bank with a few months of after-work grinding. (Also odd how the op slips in shibari reference in a tech paper.)
