I’m not a Luddite — I am in fact a big proponent of online dating. I’m a big enough fan, and know enough big enough fans, to think it’s here to stay — and that this confers upon its corporate stewards certain responsibilities. Yagan et al may be giving their customers what they want, but they’re also shaping what their customers want, and anything they do affects not just their bottom line but also how countless users experience coupling — how safe they feel, how accepted, how open they are to people they might not otherwise consider, how they treat and think about people out in the real world. They’re not just neutral meeting places where single people bring their own biases and desires. They’re managed services that can influence those biases and desires.
