Web 2.0 under the light of free software

Resumé

The development of Web 2.0 has favoured a closer relation between Internet users and the different web applications that facilitate creating, sharing and structuring digital information in a horizontal and collaborative way through so-called social software. Social software includes tools that are familiar to us all, such as chats, forums, blogs, wikis, syndication standards (RSS type), social tagging, multimedia file sharing, social networking, etc. They are tools oriented to give the user a greater capacity of interaction, and a stronger control over the content and the format in which they can be presented.
