Good point on the site’s spottiness, part of why I hesitated to give it a big fat home-page shoutout – I remember seeing it some time back, trying a search, and also concluding they still had tweaking to do. It’s a big issue in the neighborhood-news world too – aggregating information in an automated, imperfect way like “Walkscore’ does, vs. processing it with some knowledgeable human involvement (beyond the knowledge it takes for the tech, of course, and I have great respect for that, since we wouldn’t be out here on the Interwebs without the folks who found tech ways to make it accessible).
Walkability is a good topic in general, though. I agree with the “need more pockets of businesses.” Up here toward the main south end of California, for example, single-family zoning stretches for many blocks in all directions, and that may have seemed like a good thing in the days of 59-cent gas, but not any more. (At least we have a bus stop within a couple blocks.)
