"But if now there is Web 2.0, when we had Web 1.0?" This is a question that students and professors often ask me. Web 1.0 has existed ever since the Internet, but was mainly composed by textual material. With Web 1.0 the user was, in a way, limited to access and create information, since the publication of online information was limited to those who knew how to create Web pages, and had access to technologies that often were limited to the mass because of their high cost.

Wikis, Blogs and RSS are examples of how this new generation, as well as the older ones, uses these technologies to give, receive, and create information.

These companies offered assessments of their products and services online, and customers used them to write personal comments and suggestions, thus creating a network of information that was then used by the same company to improve their products and services.
The request for new methods of communication online capable of satisfying the various needs of users have facilitated the development of Web 2.0 technologies like the folksonomie, keywords that are created by those who organizes the information available online; the AJAX, that allow an interactive and dynamic use of Web applications; and feeds that make interoperable content of different applications or platforms. Summarizing, Web 2.0 is an...
