For more than eight years, Yuval Zukerman has been helping companies use the Internet to build more interactive and participative Web sites, social networks, and other Web 2.0 technologies. In this presentation he discusses how Molecular has been helping clients such as Ernst & Young on this front. And he will explain how Molecular, Boston-based interactive agency, has jumped on the blog train (Molecular.voices) and its impact on business development and marketing since its launch in 2007.
