Web 2.0 realizes and goes far beyond what Web 1.0 started. It opens tremendous opportunities as business models catch up to the technological possibilities. So many people are connected to and contribute to the Internet now that economies of scale not only lower costs, they create value.

Companies are developing business models that involve creating appealing destinations on the Web where people with shared interests can form communities. When people come together over the Web, their efforts are multiplied rather than simply added together.

Yet whether you are a seasoned business professional or a digital native, the stories about exactly how the new Web 2.0 business models work and make money may seem quite fuzzy, or even downright counterintuitive. The questions are clear:

• How is Web 2.0 different from the Web 1.0 dot-com boom and bust?
• How does Google offer “the world’s knowledge” to searchers for free and still make more than $10 billion in revenue, grow 68%, and have a stock market valuation of close to $200 billion
• What could possibly make Flickr—a two-year-old photo-sharing startup—worth $40 million to Yahoo!, a video-sharing YouTube worth $1.6 billion to Google, a social networking site called Facebook worth the equivalent of $15 billion to Microsoft?
• Is Web 2.0 about corporate blogging, wikis, and podcasting, or something else entirely?
