It is an interesting filter to use in studying where you live. I already knew my score was going to be low as I've been complaining about the walk-ability of my neighborhood since I moved here. Now I have a little map and a score of 29 (out of a 100) to show that it's just not my imagination. If I wanted easy access to schools, I would be living in the right place. If I wanted music and entertainment. Not so much.
This could be a jumping off point for a geography class in talking about place. A science class talking about environmental neighborhood design. A husband talking about moving someplace where I, ...er he, can walk to get a cup of coffee!
