BusinessWeek is surveying its readers about the best new online real estate service of 2007. Somehow Redfin didn’t even make the list of contenders, probably because we’re not available in many U.S. markets. But we’re the only ones challenging the traditional real estate industry, by actually brokering the purchase and sale of homes. The world may still need what one eye-rolling friend of mines now likes to call a YAREM (“Yet Another Real Estate Mashup”) but it absolutely cries out for someone using the Internet to change the game in real estate. Maybe next year, we’ll make the grade.
