Google Maps tends to thrive where there are lots of people, at least in my region. I live in a medium-sized town with lots of new buildings under construction, and Google Maps seems frozen in time. I even registered as Local Guide and tried adding a new restaurant in May. Still waiting. There are inexistent shops, duplicated restaurants (when they changed name, the old remains but a new one has been added next to it), and mislabeled buildings. I quit trying to work for free for Google, they take too long to accept my changes.
