"Preface The Web is no longer the sole preserve of computer science. Web 2.0 services have imbued the Web as a technical infrastructure with the imprint of human behaviour, and this has consequently attracted attention from many new fields of study including business studies, economics, information science, law, media studies, philosophy, psychology, social informatics and sociology. In fact, to understand the implications of Web 2.0, an interdisciplinary approach is needed, and in writing this book I have been influenced by Web science--a new academic discipline that studies the Web as a large, complex, engineered environment and the impact it has on society. The structure of this book is based on the iceberg model that I initially developed in 2007 as a way of thinking about Web 2.0. I have since elaborated on this and included summaries of important research areas from many different disciplines, which have been brought together as themes. To finish off, I have included a chapter on the future that both draws on the ideas presented earlier in the book and challenges readers to apply them based on what they have learned. Readership The book is aimed at an international audience, interested in forming a deeper understanding of what Web 2.0 might be and how it could develop in the future. Although it is an academic textbook, it has been written in an accessible style and parts of it can be used at an introductory undergraduate level with readers from many different backgrounds who have little knowledge of computing. In addition, parts of the book will push beyond the levels of expertise of such readers to address both computer science undergraduates and post-graduate research students, who ought to find the literature reviews in Section II to be"--



Arvustused

Besides discussing technology development and current services, parts of Andersons book address the needs of undergraduates and post-graduate research students. This book will help future researchers form a deeper understanding of what Web 2.0 is and how it could develop in the future. Web 2.0 and Beyond explains Web 2.0 and its wider context in an accessible and engaging style, helping readers, especially beginners, understand every aspect of Web 2.0 without difficulty. Yijun Gao, First Monday, Volume 17, September 2012





"Some readers may not get past this book's title and spend too much time debating what Web 2.0 might mean. Without a doubt, the web has had a dramatic impact on society. Anderson (Intelligent Content, UK), an experienced computer/technology professional, steps back and takes a long look at the web relative to the technology in the past, where it is today, and trends for the future. Chapter 1 sets the stage for the three sections that follow. Although somewhat brief, this chapter establishes the author's perspective on the web. Section 1, "The Six Big Ideas," presents the elements that come together to create a technology that will continue to grow in importance worldwide. Section 2 presents the services that form the heart of what the author refers to as Web 2.0. The third section, "Framework for the Future," is a combination of a "look under the hood" to see how the web works and the author's thoughts on where it goes from here. Each chapter ends with "Exercises and Points to Ponder" and chapter references. Readers should spend some time exploring the exercises and key points, and pay close attention to some of the thought-provoking team exercises. Recommended." J. Beidler, University of Scranton for CHOICE Magazine
