Web 1.0 consisted of a mostly read-only web with published content from content providers, while Web 2.0 enabled a wildly read-write web where users could generate and share content. Younger generations known as "NetGens" value sharing, customizing, and mixing content. Effective marketing in this new environment requires being real, relevant, and responsive. Growth comes from selling less popular, niche items through the "long tail" enabled by infinite choice and lower connection costs online. Competitive advantage comes from using data through visualization and sharing, integrating it, and leveraging social networks internally and externally. Innovation requires trying new things and learning from customers, while avoiding being risk-averse.
