The rest of the WaPo story, by Lydia DePillis, is here. Here is one excerpt:

The market for consumer-facing economists is certainly getting crowded. Big Internet companies have had chief economists for years now; Google’s Hal Varian is an oft-quoted exponent of his employer’s capabilities and worldview. Microsoft recently hired Yahoo’s former chief economist to push a more “data-driven culture” at the tech dinosaur.

But they’re not just looking for super-wonks. More importantly for Richardson, rival real estate sites Zillow, Trulia, and CoreLogic have offered their chief economists as media-friendly talking heads, always available to explain national trends: Stan Humphries, Jed Kolko, and Mark Fleming have essentially become their companies’ most visible employees, speaking at conferences and testifying on Capitol Hill. That’s why Apartmentlist.com’s recent listing for a chief economist includes the following in its job description: “Act as the face of the company with key journalists for both print and tv interviews with leading publications,” “work closely with our PR and branding teams,” and have “excellent stage presence.”
