Chapter I

1. Chapter I Introduce to Web 2.0

2. I. What is Web 2.0 • The Internet is undergoing an extreme makeover. In the 1990s and the beginning of the 21st century, the World Wide Web was primarily a place for viewers to retrieve information. The information flowed in a one-way direction. Websites were mostly built by "techie" folk who knew complex HTML coding and FTP site management. If you're scratching your head, you're not alone.

3. I. cont…. • Then around 2004 a birth of new web tools began to pop up. These tools allowed common people like us to add content to the web. People with no programming skills were suddenly publishing their own journals, photographs, videos, auctions, podcasts, wikis, slideshows and more. The web became a two-way street. Everyday people were now creating the content.By 2007, a second generation of the web had taken over - Web 2.0. Also known as the Read/Write Web, the new web is a breeding ground for creative and engaging educational endeavors.

4. I.cont…. • Teachers are using the new Web 2.0 tools to launch their classroom into the 21st century. Students are creating online content, collaborating with other students around the world and showcasing their work to a global audience. Web 2.0 facilitates professional networking. It provides authentic learning experiences for students, and it encourages global awareness, creativity, innovation, critical thinking and collaboration. The knowledge our students will gain from engaging with Web 2.0 technologies will foster the communication and information literacy skills that are required in the 21st century.The great thing about Web 2.0 tools is they are easy to use. Really. And it's all free. Take some time to follow the links on the side, and you will soon be merging onto the information superhighway.

5. II. Why Web 2.0 Matters • 1. The Focus of Technology Moves To People With Web 2.0.  One of the lessons the software industry relearns every generation is thatit's always a people problem.  It's not that people are the actual problem of course.  It's when software developers naively use technology to try to solve our problems instead of addressing the underlying issues that people are actually facing.    And Web 2.0 gives us very specific techniques to do this and attempts to address the "people problem" directly.

6. 2. Web 2.0 Represents Best Practices.  The ideas in the Web 2.0 toolbox were not pulled from thin air.  In fact, they were systematically identified by what actually worked during the first generation of the Web.  Web 2.0 contains proven techniques for building valuable Web-based software and experiences.  The originalDesign Patterns book was one of the most popular books of its time because it at long last represented distilled knowledge of how to design software with ideas couched in a form that were reusable and accessible.  So too are the Web 2.0 best practices.  If you want to make software deliver the very best content and functionality to its users, Web 2.0 is an ideal place to start.

7. 3. Web 2.0 Has Excellent FengShui.  Why does this matter?  It has to do with critical massandsynergy, two vital value creation forces.  Taken individually, Web 2.0 techniques like harnessing collective intelligence, radical decentralization, The Long Tail are quite powerful, but they all have a potency much greater than their simple sum and they strongly reinforce each other. 

8. 4. Quality Is Maximized, Waste Is Minimized.  The software world is going through one of its cyclical crises as development jobs go overseas and older, more bloated ways of building software finishimploding as the latest software techniques become more agileandlightweight (sometimes called lean).  The guys over at 37Signals say it best...  Using Web 2.0 you can build better software with less people,less money, less abstractions, less effort, and with this increase in constraints you get cleaner, more satisfying software as the result.  And simpler software is invariably higher quality.

9. 5. Web 2.0 Has A Ballistic Trajectory.  Never count out the momentum of a rapidly emerging idea.  For example, I'm a huge fan of Eric Evans' Domain Driven Design but it's so obscure that it will probably never get off the ground in a big way. There's no buzz, excitement, or even a general marketplace for it.  This is Web 2.0's time in the sun, deserved or not.  You can use the leviathan forces of attention and enthusiasm that are swirling around Web 2.0 these days as a powerful enabler to make something important and exciting happen in your organization.  Use this opportunity to seize the initiative, ride the wave, and build great software that matters.

10. III. What is Web 2.0 technology? • Web 2.0 is the term used to describe a variety of web sites and applications that allow anyone to create and share online information or material they have created. A key element of the technology is that it allows people to create, share, collaborate & communicate. Web 2.0 differs from other types of websites as it does not require any web design or publishing skills to participate, making it easy for people to create and publish or communicate their work to the world.

11. The nature of this technology makes it an easy and popular way to communicate information to either a select group of people or to a much wider audience. The University can make use of these tools to communicate with students, staff and the wider academic community. It can also be an effective way to communicate and interact with students and research colleagues. • There are number of different types of web 2.0 applications including wikis, blogs, social networking, folksonomies, podcasting & content hosting services. Many of the most popular websites are Web 2.0 sites such as Wikipedia, YouTube, Facebook, MySpace, Flickr.
