Walk Score In The Wall Street Journal

It doesn't get much more mainstream than this - walkability is covered in the WSJ's Real Estate section: A Walker's Guide to Home Buying

Still, the more emphasis on walking distance, the better, say many home-buyers. Gary Howe, a photographer and writer in Traverse City, Mich., has been working with his city's planning department to get, among other things, pedestrian-enhanced crosswalks at a busy intersection—a crossing so dangerous, he says, that many neighbors drive less than a block to a pharmacy just to avoid that street. "When I was looking for a house four years ago, lots of real-estate agents didn't even mention walkability," Mr. Howe says. "Now I see it everywhere, which is great."
