Ask my generation the first thing they think of when you say the word ‘swipe’. In all likelihood, the answer will be ‘Tinder’. Launched in 2012, Tinder is a mobile app where you’re presented images of people that live near you and you can ‘swipe left’ to to reject someone or ‘swipe right’ to show you’re interested. The magic to Tinder lies is its ‘double opt-in’ mechanism: both parties must swipe right in order to start talking with eachother. This is supposed to alleviate the pressure of approaching someone you’re interested in, but not knowing if that interest is reciprocated.
