Who is the target market?

I really think this could be useful for not the average user but traveling service professionals. By looking at this data they can figure out where they are most of the time and maybe even create alternate routes or stations based on the hot spots.

Frankly, the average home user is more concerned with the amount of time they spend on the tasks rather than location. I believe RescueTime does something similar to what I am describing for the end user.
