I often wonder if it would be possible to do any kind of serious study into urban morphology without the help of Google Earth. I know it has been indispensable to my studies, perhaps as indispensable as the microscope is to biologists. Google Earth is our macroscope, it allows us to see what is too large to see with the naked eye.
I will, but not very often. After something grows big, there comes to be a point where you contribute more by removing things than by adding more.
