1. What is…

2. A Little History…  The term “Web 2.0” was familiarized when Tim O’Reilly hosted the first Web 2.0 conference in 2004  This Link (a characteristic of Web 2.0) includes some footage of the conferenceLink

3. So what is it?  Web 2.0 isn’t a thing, it’s a state of mind.  It’s also a Buzzword, but Buzzwords have their uses:  Good for non-technical people  Eases communication  A good way to promote a group of technologies

4. Web 2.0 also…  Provides a service, not a product (infoware not software)  Encourages user contribution (reviews, comments)  Makes it easy to re-use and re-mix  Provides community and sense of ownership as well as customer self-service

5. So what is it…really?  Web 2.0 is associated with web applications that encourage interactive information sharing.  Web 2.0 sites provide their users with dissemination capabilities, information storage and creation  In a nutshell, Web 2.0 allows users to do more than just retrieve the information or message.

6. Document Delivery vs Platforms  The web is changing from a document delivery system to an application platform  The Web as a platform:  Simplifies distribution  Easy way of maintaining code  Faster speed to market  Share data across devices

7. So, what’s the difference?  Web 1.0 refers to former business models (Encyclopedia Britannica) which was one way communication  Web 2.0 offers two way communication between users and businesses and users can often build your business (Twitter and WordPress)

8. So, what’s the difference again?  O’Reilly compared Web 1.0 to Google which is now a business and not so based on the creation of software (browsers) but instead provides services based on data (users)  Instead of just having users receive information, they can build upon it (Wikipedia)

10. Characteristics of Web 2.0  Rich User Experience (interaction)  User Participation (input)  Dynamic Content (many authors, not just one)  Metadata (clarification)  Web standards and scalability (google analytics)  Participation (output)

11. How do I know it’s Web 2.0?  Web 2.0 sites typically include some, if not all, of the following features:  Search (finding info through keywords)  Links (guides to related info)  Authoring (the ability to create and update = collaborative work)  Tags (filtering by words)  Extensions (web applications = document server)  Signals (RSS feeds)

12. Core Competencies of Web 2.0 Companies  Services, not packaged software, with cost effective scalability  Control over unique, hard-to-create data sources that get richer as more people use them  Trusting users as co-developers  Harnessing collective intelligence  Leveraging the long tail through customer self- service  Lightweight user interfaces, development models, AND business models

13. Web 2.0 = Ajax  Ajax is shorthand for asynchronous JavaScript + XML (say that 3x fast)  A group of interrelated web development techniques used on the client-side to create interactive web applications.  With Ajax, web applications can retrieve data from the server without interfering with the display and behavior of the existing page

14. The evolution…  In lay mans terms, this is the present and future of the World Wide Web.this
