Web 2.0 has evolved communication methods far beyond just email. It allows for peer-to-peer sharing of information like files, words, images and audio in a multi-media format with few gatekeepers. This social aspect of Web 2.0 has massive impacts on business and society, changing industries like music and travel. Businesses that are aware of these changes and tools available on the web like blogs, RSS feeds, and image sharing can both soften impacts and benefit from the new opportunities.
