Low: A 1-10 Rating System
One of the perks of an online app like Grindr is that you can hit on people who might be "out of your league" without the sting of rejection. I mean, not entirely without the sting of rejection, but hey, getting ignored is way less painful than a face-to-face rebuff at a bar or something.
I'm already worried people are going to weaponise this rating system. Can you imagine messaging someone, sending a few additional selfies, or even sharing personal explicit photographs only to be answered with nothing but a "2"? I'm, like, pre-emptively ready to binge-eat ice cream and cry while looking at myself in the mirror.
