When we talk about Web 2.0 or the Social Web, we refer to a model of Web pages that facilitate the transmission of information , interoperability and collaboration among its users , through a design focused on their needs, rather than those of the company. In other words, it is a trend on the Internet that advocates a more interactive network, less one-sided, in which users do not occupy a merely passive role.
Web 2.0 is a step forward in the evolution of the Internet , to incorporate the user as an active agent in its operation, and not as a mere client or recipient of the information. This happens through dynamic websites, in which the user is allowed to interact, generate content, or be part of virtual communities .
The term originated in 2004 , a product of Tim O’Reilly’s lecture on the future of the Internet, and plays with the usual name for computer programs (1.0, 1.1., 1.2, 2.0, etc.) as they are updated and get better. However, it does not really refer to a technical improvement of the network , as to a different way of understanding it.
All of them have in common a disposition towards interactivity and the construction of a sense of community between people who may be strangers or thousands of miles apart.
