Web 2.0

technology Maturity 9-11 Next article →

Web 2.0 refers to a specific era of the World Wide Web defined by interactivity and participation. It is also known as the participatory web or the social web. Unlike the earlier version of the internet, Web 2.0 emphasizes user-generated content. This means that the people visiting a website are also the ones creating its material. These platforms focus on ease of use and interoperability, which is the ability to work across different products and devices.

By turning users into creators, Web 2.0 transformed the internet into a massive virtual community.

The mechanism of Web 2.0 relies on an "architecture of participation." In this system, the website becomes a platform that grows more valuable as more people use it. Users contribute by uploading videos, writing blog posts, or leaving comments on articles. This creates dynamic content that changes constantly. This process is often described as "the perpetual beta," where services are updated continuously rather than through scheduled software releases. As users provide data and interact, the platform evolves to meet their needs. This creates a cycle where user activity directly drives the development of the service.

There are many distinct types of Web 2.0 applications. Social networking sites, such as Facebook, allow users to build profiles and connect with others. Video sharing sites like YouTube enable anyone to host and share multimedia content. Wikis are collaborative tools where many people can write and edit the same pages. Another feature is the folksonomy, which is a system of "tagging" keywords to organize links, photos, or videos. There are also mashup applications, which combine data from different sources into one new tool. Even consumer-evaluation platforms like Amazon and eBay use these collaborative principles to function.

The history of the term began with Darcy DiNucci, an information architecture consultant. She coined the term "Web 2.0" in a 1999 article titled "Fragmented Future." At that time, she was observing how the web was moving beyond the traditional desktop computer. The term did not resurface widely until 2002. In 2004, Tim O'Reilly and Dale Dougherty popularized the concept at the first Web 2.0 Conference. They described the web as a platform where software runs in the browser instead of on a desktop. This shift changed how businesses viewed their customers, as users began building the value of the service through their own actions.

To understand the significance of this shift, one must compare it to the Web 1.0 era. Web 1.0 lasted from roughly 1989 to 2004 and was characterized by static pages. During that time, content creators were few, and most users were merely passive consumers. Web 1.0 sites used older technologies like HTML 3.2, frames, and tables to display information. Feedback was limited to things like guestbooks or "mailto" forms that opened an email client. In contrast, Web 2.0 uses relational database management systems (RDBMS) to serve dynamic content. This allows for the massive scale of interaction seen in modern social media and cloud computing.

Notable examples of this transition can be seen in how information is managed. For instance, the Encyclopædia Britannica Online was a Web 1.0 style model that relied on experts to write and release content. Wikipedia, however, is the epitome of Web 2.0. It relies on a community of volunteer editors to constantly update and fix articles. Wikipedia follows the adage that "given enough eyeballs, all bugs are shallow," meaning many users can find and fix errors quickly.

This collaborative model allows for a massive amount of information to be maintained without a central group of experts.

Web 2.0 connects to broader technological and social concepts. It is closely linked to the idea of the "network as platform," where the internet provides the infrastructure for applications and file storage. Some scholars also link it to cloud computing, as both rely on internet-based resources. However, the term has faced criticism. Tim Berners-Lee, the inventor of the World Wide Web, has called "Web 2.0" a piece of jargon. He prefers to view the web as a collaborative medium for reading and writing. He also proposed the "Semantic Web," or Web 3.0, where machines can process the actual meaning of web content.
