Concerning "dating apps suck": OkCupid was decent in its heyday. But even at that time, there were very few users of it near the city where I lived or even in the country where I lived. Thus, it simply was nevertheless not useful to me. But no other dating site uses a similar algorithm; perhaps most people care about other things in dating than what OkCupid is optimized to give them.
