I was complaining about the lack of a scale on Google maps, and one of my friends pointed me to a
pedometer. It is pretty cool. A very useful feature to measure distances by clicking points on a map. Cool interface too. But, Google still needs to add a scale to their maps so that one can get an idea of the 'scale', for a lack of words, of the map. At least, we have APIs that we can use and enhance/add functionality.
