According to Zahn, the things that pop up can include Waze users reporting that a one-way street is now two-way or even a surprise road closure. It's his job to update the map accordingly. Zahn's responsibilities are numerous enough that the 27-year-old also puts in time over the weekends and for about two hours each night as he and his wife watch TV— Bones or The Big Bang Theory, usually.
Zahn has recently had to scale back because he is enrolled in graduate school, but he still puts in at least 16 hours a week working for Waze, which is “more than my wife would like,” he says. That's because he doesn't get paid for any of his time. And he isn't alone. Zahn is just one of roughly 6,000 active editors throughout the U.S. who voluntarily keep Waze's map updated. Internationally, there are almost 300,000 editors working behind the scenes. For the most part, this volunteer workforce is entirely self-sufficient.
I love Waze, and I love my wife, and she loves me, though most definitely not so much that she'd stay with me if I loved Waze so much that I worked on it pro bono for 2 hours a night.
