I wonder if it's just me or does the complaint concerns mostly oc cupid, which is very data obsessed. For example Tinder, a far more successful online dating tool seems to be much much simpler in purpose and not suffering from those problems. In other words - I think it's specific to data obsessed nerds take on online dating and not the problem with online dating at all :-)
I'd assume older singles pursuing more serious companionship would gravitate towards the eharmony, match, okcupid type sites.
