Web 2.0 > web 1.0
Web 2.0 is defined as an intersection of web application features that facilitate participatory information sharing, interoperability, user-centered design, and collaboration on the World Wide Web. A Web 2.0 site allows users to interact and collaborate with each other in a social media as creators of user-generated content in a online community, in contrast to websites where users are limited to the passive viewing of content that was created for them. Examples of Web 2.0 include social networking sites, blogs, wikis, video sharing sites, hosted services, web applications, mashups and folksonomies.
The term is associated with Tim O’Reilly because of the O’Reilly Media Web 2.0 conference in 2004. Although the term speaks of a new version of the World Wide Web, it does not refer to an update to any technical specification, but rather to increasing changes in the ways software developers and end-users use the Web.
Web 2.0 websites allow users to do more than just gain information. By increasing what was already possible in Web 1.0, they provide the user with more user-interface, software and storage facilities, all through their browser. This has been called “Network as platform” computing. Users can provide the data that is on a Web 2.0 site and exercise some control over that very data. These sites may have an architecture of participation that encourages users to add value to the application as they use it. Some experts have made the case that cloud computing is a form of Web 2.0 because cloud computing is basicly an implication of computing on the Internet.
The Web 2.0 offers all users the same freedom to contribute. While this opens the possibility for rational debate and collaboration, it also opens the possibility for “spamming” and “trolling” by less rational users. The impossibility of excluding group members who don’t contribute to the provision of goods from sharing profits gives rise to the possibility that rational members will prefer to withhold their contribution of effort and free load on the contribution of others.This requires what is sometimes called radical trust by the management or creator of the website. According to Best, the characteristics of Web 2.0 are: rich user experience, user participation, dynamic content, metadata, web standards and scalability. Further characteristics, such as openness, freedom and collective intelligence by way of user participation, can also be viewed as essential attributes of Web 2.0.
A very great example of a Web 2.0 website is wordpress and Ds106. WordPress it’s self is a blogging website that allows people to share and recieve knowledge, while having the capability to edit and post any array of things available out there. Ds106 is a free create website where you can post your own projects, create your own, and do already made projects available.
