WEB 2.0

The Internet, until some time ago, was characterized almost exclusively of static content - full plain pages of information. The user did not have the power to interact, to comment or to share with others. The web community grew and the internet became our first choice for searching information, the web is not anymore attached to one big web site, but instead, different sites are sharing files and information.

The web 2.0 could be defined as a huge network where users can divide content and services, increasing the interactivity and allowing each one of us to share our personal experiences. One great thing about the web 2.0 is that our own content can feed this network and people can see and evaluate, helping to establish a better association of information.

There are some characteristics that help to create the idea of Web 2.0 applications. In most of these applications we can TAG words, images and all kind of information. The act of tagging things on the web help to construct comminutes and social environments. Tagging is like putting keywords in things, so people can search for these keywords later and share their ideas. The RSS feed is another example, XML files with headlines and news that facilitate the access to information.

Here are some good sites that illustrate the Web 2.0 concept:
- NetVibes, a web site that allows the users to create their own web page, with an incredible diversity of objects and components;
- Orkut: a web community where web users can share information about themselves.
- Second Life: a 3D world where people can interact and share knowledge.

As we can see, today on the web, the user has the main role, creating and sharing information, experiences and lives.
