This week, we're going to examine how agents can use social networks to market themselves. Some of the issues we're likely to explore include:* With some of the new social networks for real estate launching recently (like MyDealBook & RealSeakr), how are they trying to differentiate themselves? And what chance do they have for adoption? * What should real estate professionals look for in a social network?* What are some keys to success for social networks trying to reach into the agent community?* Who does well in micro-blogging environments like Twitter and Plunk?
