It's no secret that the Google Maps API is incredibly popular. Our directory lists over 2,100 Google Maps mashups, but that's obviously just a subset of all the sites powered by the mapping platform. And now we know how many sites that is. According to Google Developer Advocate Mano Marks, there are 350,000 websites incorporating Google Maps. And, of course, Google now has many other geographic APIs.
