Zillow will not mean the end of real estate agents. But the company is changing the way agents do their jobs. That's what Zillow CEO Spencer Rascoff and Chief Economist Stan Humphries argue in the new book "Zillow Talk: The New Rules of Real Estate." Real estate agents are still relevant despite the wealth of industry information available to consumers online, they said. Zillow may be leading the charge, pulling relevant information on home listings together into one place. But it's the Internet that's really shaping the future of the real estate industry. No one — not Zillow or real estate agents — disputes this. They just see the industry's changes through a slightly different lens.
