Met my girlfriend through OK cupid too, and had the same experience. But I can tell you the app got tinderfied over the years. Used to be you’d just be able to message people and see how you matched from looking up. When I last used it it already hid people behind a swipe system, only allowing people to talk when they both had swiped right. The swiping apps usually feel they’re used by people less interested in what I wanted. For op I’d tell him to use OK cupid if he likes to answer those profiling questions and wants to find someone who also does. For swiping, tinder works best.
