What's your boss's house worth? Zillow can tell you

This article rightly points out how inaccurate/incomplete the information on this home valuator site, Zillow, is, but this site is still very valuable. It's valuable because it's created a model for how a home valuator should work. The inconsistencies will be worked out and eventually this will be the standard. It's a bit scary for people who hold on to and protect their personal financial information like their life depended on it, but transparency is coming.
