They should take climate into consideration. My apartment in Madison, Wisconsin scores 92/100. I'd generally agree with this, but when it's 15 degrees Fahrenheit on your walk to work... Brr.
Cool idea, but I agree that the implementation needs work. The score for my office is 68, but it is really not walkable at all. Whereas the score for my home is only a 62, but I never need to use a car at home.
Cool 1550 Crystal Drive Arlington VA 22202 = 85 ;) Not bad for the east cost IMO.
Granted, I walk to work and my home address is only 77 so it's a little off. Hmm, it looks like it's missing a lot of stores and a mall so it's not that bad.
Hmm... The area I live in Columbus, OH has a 80/100! Though some of the information is outdated, I saw two stores - one pharmacy and one hardware store that closed down some time ago that might have thrown the score off...
Hey! I followed your profile which took me to your website. Very impressive. If you ever want to meet for a cup of coffee, drop me a line, would love to talk to a fellow hacker from Columbus.
