Ask HN: Why don't we bring back old school OkCupid?

Trademark issues aside... why do we do this swipe culture crap? Old school OkCupud was darkly beautiful because it told you your best match was -- who cares if they're a mafia princess or work down at the cloud factory or simply have other suitors ;-) What is stopping someone, aside from patents, from making a match based dating site to compete with the current market?
