If you're 20-something and single, you have probably used the dating site OkCupid before, even it was just to "see what's out there" on your friend’s account when they weren’t paying attention.
For those of you who aren’t familiar with the concept of the site because you've been with the same partner for nearly a decade, OkCupid works by having each new user answer a series of questions ranging from “Do you Google someone before a first date?” to “Which is more offensive: book burning or flag burning?”
The site then calculates a “match percentage” between any two users, based on each user’s answers to the questions in order to provide users with an idea of how compatible they are with everyone who messages them.
Who comes up with this stuff? Harvard graduate Christian Rudder founded OkCupid in 2004, along with three of his co-workers he met at his former job, Sparknotes, in 1999.
“We are all matchmakers, and we were looking at the dating industry and thought it could use some more analysis. We wanted to match users based on more than just ‘you are both 25 and live in New York’," says Rudder.
