Introduction Introduction In studying and/or promoting web-technology, the phrase Web 2.0 can refer to a perceived second generation of web-based communities and hosted services-such as social-networking sites, wikis, and folksonomies-which aim to facilitate creativity, collaboration, and sharing between users. The term gained currency following the first O'Reilly Media Web 2.0 conference in 2004. Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users use the web. -Wikipedia The emergence of Web 2.0 isn't tied to a specific technology or tool. It's a collection of advanced capabilities growing out of technologies such as Java, Ajax, and specialized markup languages that simplify sharing and repurposing of web content.
These rich and interactive features change the web experience in notable ways: They allow users to participate without regard to geography They democratize information They allow new ideas, products, and features to emerge The change in the nature of how content is created and these next-generation features are ushering in new opportunities for marketing, customer service, business intelligence, and internal communication. Web 2.0 is perhaps most evident in the consumer marketplace with social networking sites, mash ups, and video sharing services. This is the "play" part of Web 2.0. But this collaborative technology will make huge advances in the business effectiveness with online collaborative tools. Just as users play a key role in a consumer-based Web 2.0 world of blogs, wikis, communities, and collaboration, they, and the content they create, are critical to the success of Web 2.
0 in business as well. Blogs, for example, are changing the marketing landscape and provide an exciting new way to gain valuable customer feedback. Wikis create valuable enterprise knowledge management assets, enabling improved customer service. Bookmarking and folksonomies enable an organization to share information and to define and tag content in ways that facilitate and accelerate search and retrieval. Photos and videos make content more visual, more personal, and more human. They can also become a valuable business asset: a customer video testimonial from a known expert helps sell product. Web 2.0 technologies enable more effective collaboration and knowledge-sharing, improve decision-making, and accelerate productivity and problem-solving among employees, partners, and customers.
Collaborative technologies are key enablers, increasing productivity and reducing travel time and expense. More importantly, collaborative technologies enable business managers to re-engineer and transform their business function, department, or process to reap the business value Web 2.0 and the Mobile Web can enable. Goals, Objectives, and Approach A little into the writing of the book, we realized that Web 2.0 is very vast and could fill a thousand-page book! So our challenge was to see what areas we should leave out to cut through the hyperbole, the hype, the billion dollar valuations, and the security threats and still provide the readers with an introduction to the social and business characteristics of Web 2.0 as well as a glimpse of the technologies behind it. Another challenge we had was to get the right level of detail on the topics we selected. We wanted this book to be not a guided tour but a hitchhiking experience, where sometimes the stops are quick (as in a quick look at UI or wikis), sometimes the detours linger longer (such as in social networking and cloud computing), and sometimes you need to dig deeper via the hundreds of links and references to experience the inner details.
Many of you already have some exposure to various pieces of Web 2.0, but few have a full appreciation for all the vectors of Web 2.0. In this book, we aim to provide a cohesive, coherent view of both the underlying technologies and the potential applications to bring readers up to speed and spark creative ideas about how to apply Web 2.0. This book does not have ROI calculations or project plans. It also does not rely on extensive code fragments or programming aspects. The major challenge we faced was of omission rather than inclusion.
We had to find those key pieces of Web 2.0 that would make an enterprise tick. An complete understanding of Web 2.0 does not come just from reading a book. One has to also experience the various collaborative formats that make up Web 2.0 by creating an account in facebook.com, developing a wiki, or reading a blog about some topics of interest, or better yet by writing a blog or participating in a collaboration-based wiki. Who Should Read This Book? The primary target audience is anyone who has a need to understand Web 2.
0 technologies. This includes program managers, marketing managers, business analysts, IT analysts, and so on, who either have to market Web 2.0 or understand enough to engage in Web 2.0 systems development. The audience also includes executives, in any field, who need to understand the Web 2.0 phenomenon. A secondary audience is the engineers who are working on traditional legacy systems and who want to understand the opportunities Web 2.0 brings.
They need an in-depth conceptual view to see how everything fits and also an evaluation of the hottest technologies. This book does not assume any special knowledge other than general computer literacy and an awareness of the Internet and the web. Strategies for Experiencing Web 2.0 Using Web 2.0 is like swimming: You cannot really learn it or in this case understand it by standing on the l∧ you need to immerse yourself in it. We have included many reference URLs to visit that will give you more in-depth information on various aspects of Web 2.0. We urge you to visit these URLs.
They are listed in the appendix. You can find an electronic version of the appendix, with all the URLs conveniently hot linked, at the book's website. Keep in mind that because of the dynamic nature of the web, some links might no longer function depending on when you are reading this book.

How This Book Is Organized Although you can read any chapter alone and get a full understanding of that particular aspect of Web 2.
0, we recommend you read Chapter 1, "An Introduction to Web 2.0," which outlines Web 2.0 and gives you an overview of Web 2.0 that should enable you to see how the pieces fit together.
