Web 2.0 is a new way of thinking about software that emphasizes user participation, openness, and network effects to create a more mature Internet. Companies can benefit from Web 2.0 by gaining measurable increases in innovation, knowledge, lower costs, and higher revenues by tightly integrating these technologies. Web 2.0 tools present vast opportunities for companies if they know how to use technologies like social networking sites, which now attract over 100 million monthly users, to engage consumers and harness creativity internally.
