Introduction “Web 1.0 was about connecting computers and making technology more efficient for computers. Web 2.0 is about connecting people and making technology efficient for people.” (Dan Zambonini)
Web 2.0 and Social Computing Web 1.0 was released in the early 1993 to 2001. The term www occurred due to the burst of the DOT-com bubble in 2001. Since 2004, Web 2.0 was used for current web design, business models and branding methods of sites on the World Wide Web.
Web 2.0 and Social Computing Web 2.0 can be broadly defined as a web application that facilitates interactive information sharing, interoperability, user-centered design and collaboration on the World Wide Web. Tim O’Reilly defined it as “Like many important concepts, Web 2.0 doesn't have a hard boundary, but rather, a gravitational core. You can visualize Web 2.0 as a set of principles and practices that tie together a veritable solar system of sites that demonstrate some or all of those principles, at a varying distance from that core.”
Characteristics of Web 2.0 User centered design
A web design which is created in a way that it fulfills every possible need of the end user and empowers the user to perform certain customizations within the design.
User-centered designs are cleaner, often ajax based and easy to navigate. The appearance of the design is given a special preference while creating such a design.
Example: iGoogle, a customizable Google homepage.
Characteristics of Web 2.0 Crowd-sourcing
Every small unit of contribution is important to a Web 2.0 service. Millions of such contributions eventually lead the website to state of higher relevance.
For example, blogging platforms like Blogger and WordPresshave millions of users acting as contributors.
Characteristics of Web 2.0 Web as platform - Web 2.0 services do not require a client download condition. Also there is no dependency on a particular OS for accessing the web services. Whatever be the method of internet access (Windows, Mac or Mobile OS), the web 2.0 applications are not affected.
Earlier, most of the services used to be administered and not automated.
But Web 2.0 services follow a self-service model rather than being an administrator dependent.
For example, Google Adsense is a self service platform for Ad publishing
Characteristics of Web 2.0 Dynamic content
Web 2.0 services have to be highly dynamic and proactive.
In fact since Web 2.0 allows for crowd sourcing, it is of utmost importance to have dynamicity
Characteristics of Web 2.0 Rich user experience
Use of XHTML, CSS 2.0, Ajax, flex, HTML5 and similar other rich media producing technologies have potentially helped making web services lighter, faster, less cluttered and more appealing to the end user.
A great user experience plays a big role today, in making users come back again to the web service.
