Earlier quoted context omitted.
Maybe, but anyone who would elect to use a "speed dating" app probably does.
The point of speed dating is to meet a lot of people quickly in the hope that you'll find someone who has chemistry with you. It's about personality, not sex.
Speaking about chemistry ... I'm hoping for an app that can use pheromones to match people. Or genotyping, or both (I suppose pheromones correlate with DNA somehow). Am I the only one who finds smell most important?
