To help focus on quality instead of quantity, there should be more to it than a mere swipe. Maybe each individual match should be given an idea of where to continue through tags, or a slider like the interest one. They want to talk, they want to go on a date, they think you are attractive, they want to hang out, they want to have fun, grab ice cream, stuff like that... The interest slider doesn’t help much. It should be more individual for each match.
