I think it's also a place where men can boost their self esteem. I think it's the antithesis of seduction. It's just way too efficient and not serendipitous enough. Sure, you can say swiping on someone allows you to interact with way more people than you could ever interact with in person. The thing that's lost is that random look in the middle of the street, coffee shop, or party where you exchange glances with a stranger and wonder for a second if the attraction is mutual. Then you put yourself out there without knowing what the response would be because you don't know if the person is looking for a tryst or romance. On tinder, you can assume they're already open to at least some flirting. If not, no big deal -- you never even looked the person in the eyes.
