Through social tools everyone can share any kind of information. People are involved in what Henry Jenkins calls participatory culture:
A participatory culture is a culture with relatively low barriers to artistic expression and civic engagement, strong support for creating and sharing one’s creations, and some type of informal mentorship whereby what is known by the most experienced is passed along to novices. A participatory culture is also one in which members believe their contributions matter, and feel some degree of social connection with one another.
Among the new capabilities related to Information Literacy, Jenkins mentions Appropriation, the ability to meaningfully sample and remix media content; Judgment, the ability to evaluate the reliability and credibility of different information sources; Networking, the ability to search for, synthesize, and disseminate information.
WEB 1.0 is a retronym referring to the first stage of the World Wide Web's evolution, from roughly 1991 to 2004 was based on the paper document model and the top-down transmission of knowledge, where an elite of people produces and disseminates information and is responsible for the data organization process, in a producer-consumer dynamic.
In the Web 2.0 refers to websites that emphasize user-generated content, ease of use, participatory culture and interoperability for end users, with the advent of Interactive technologies that facilitate the online creation or sharing of information, ideas, and other forms of expression the process is reversed and becomes bottom-up, it is the user who processes the information into categories: the consumer also becomes a content producer. In this new perspective, the user becomes a A person who consumes and produces a product.
