MIT, Wharton, Pearson, and Shared Insights have developed a very interesting project. They have set up a wiki allowing a community of people to write a business book that will be published by Pearson in the fall. The overall premise is that communities can augment or even replace certain traditional business efforts. Marketing has emerged as the leading area for such efforts. I wrote a short section on the power of word of mouth in service marketing. The preliminary results will be shared at the Community 2.0 conference next week in Las Vegas.
