Web 2.0 is associated with the possibilities of interaction.
Web 2.0 is a concept that was coined in 2003 and refers to the social phenomenon that emerged from the development of various applications on the Internet . The term establishes a distinction between the first era of the Web (where the user was basically a passive subject who received information or published it, without there being too many possibilities for interaction to be generated) and the revolution that led to the rise of blogs, social networks and other related tools.
Web 2.0, therefore, is made up of platforms for publishing content, such as Blogger ; social networks, such as Facebook ; services known as wikis ( Wikipedia ); and photo, audio or video hosting portals ( Flickr , YouTube ). The essence of these tools is the possibility of interacting with other users or providing content that enriches the browsing experience.
Features of Web 2.0
It is important to keep in mind that there is no precise definition of Web 2.0, although it is possible to approximate it by establishing certain parameters . A web page that is limited to displaying information and that is not even updated is part of generation 1.0. On the other hand, when pages offer a considerable level of interaction and are updated with user contributions, we speak of Web 2.0.
It is worth mentioning that the differences between the first and second eras of the Web are not based on a technological change in the servers, although naturally there has been considerable progress in hardware; It is the Network's approach, objectives and the way in which users began to perceive online information that characterizes this rebirth, which took place quietly but quickly at the beginning of the new millennium.
Until then, the Internet was a universe of mostly static data, a revolutionary source of consultation that attracted millions of people to passively contemplate it. Although forums and chat date back to Web 1.0, they were well differentiated from traditional sites (as is the case today); Browsing was similar to visiting a large shopping center, with countless stores, in which it was possible to buy products, but not alter their windows.
Platforms such as YouTube and Flickr are part of the so-called Web 2.0.
A social phenomenon
With the arrival of Web 2.0, a social phenomenon occurred that forever changed our relationship with information, mainly because it made us part of it : nowadays, a news story about a demonstration against animal abuse is not complete without show how many Facebook users read and enjoyed it, what percentage of readers are in favor of the movement, and the comments, which often provide important data or point out errors.
As with any milestone in the history of humanity, the democracy associated with Web 2.0 has seriously impacted traditional media, mainly those that did not know how to adapt to this new wave of freedoms. The last decade has seen the birth of various independent newspapers and magazines that have managed to establish themselves and achieve great success worldwide, contrary to the decline of former colossi.
Negative aspects of Web 2.0 and its evolution
It is not easy for journalists to accept that under an article that took them days of research and preparation, users have the right to insult and despise them, to threaten their families or to post photomontages with their faces; But these are some of the negative consequences of Web 2.0, and only by accepting them and cleverly avoiding abuse is it possible to achieve success without dying in the attempt .
Some experts associate Web 3.0 with the Semantic Web , which consists of the inclusion of semantic or ontological metadata (describing the contents and relationships between data) so that they can be tracked by processing systems.
