I recommended OkCupid to a girl, and she used the question-answer matching system. She found a guy, then married him!
Think about this, if a #dating app matched people with the appropriate mate, quickly, they would NOT be required to go on hundreds of #dates. But then the dating app would lose money.
You are right. The economic incentives are misaligned, similar to doctors treating a disease instead of curing it. But in this particular case, the couple found each other.
