Web 2.0 is a system in which internet content is created not by authors who have suitable tools and the necessary knowledge, but by the users and visitors of the website themselves.
They publish their own works under their own name and take part in creating internet content. This lowers the quality of internet content, but makes it accessible to wider masses of users. The internet thus grows every day by millions of articles and pieces of data.
Web 2.0 therefore comprises all user internet services, such as creating a blog, writing comments, sharing files, insights or photos, using social networks, editing documents and much more.
