It discusses Walmart's history as a community store, how geography no longer confines community, and how Walmart now connects through various social media touchpoints like YouTube, blogs, mobile, and social networks. It also outlines how Walmart's customer community helps people save money and live better, and provides examples of how Walmart engages stakeholders through blogs, Twitter, and an internal social network for associates called mywalmart.
