#web 2.0 and marketing

I found an interesting video. In this video, "...Seth Godin explains how web 2.0 and social networks can help marketers build a new kind of relationship with their customers.". Here is the link, www.bnet.com/2422-13723_23-162360.html. I think web 2.0 fundamentally changed the way marketers communicate with their customers and deliver customer value in a much more efficient way.
