Web 2.0 is a content publishing platform, 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 the rest of the users or contributing content that enriches the browsing experience.
There is no precise definition of Web 2.0, although it is possible to approach it by setting specific parameters. A web page that is limited to displaying information and is not even updated is part of the 1.0 generation.

The last decade has seen the birth of various independent newspapers and magazines that have managed to establish themselves and achieve great success worldwide. As opposed to the decline of former colossi.
It is not easy for journalists to accept that under an article that took days of investigation and elaboration. Users have the right to insult and despise them, threaten their families. Still, these are some of the negative consequences of Web 2.0, and only by accepting them. And shrewdly avoiding abuse can success be achieved without dying in the attempt.
