I thought Tinder's inherent mutual interest-based design was a step in a good direction for online dating. I had to set my okcupid profile to "women only" and then eventually deleted it because I was really tired of men I have nothing in common with messaging and harassing me. Forget other sites - they weren't any better. Mutual interest is a powerful thing. If overanalyzing Tinder will help create better dating apps so be it, we'll all be better off for it.

disclaimer: I know a Tinder co-founder (not the one in question) but I'm married anyway, not in the dating pool ;)

Dumb apps, products and services do incredible complex social things and have involved consequences to our psychology all the time -- even without any specific intent from their owners.

It's not because the apps are smart and complex -- it's because WE, humans, are smart and complex.
