Web 2.0 how much will it change?

The articles "Why Web 2.0 is important to higher education?" and "Web 2.0: A new wave of innovation for Teaching and Learning" both acknowledge the arrival of this new technology Web 2.0. They both believe that it has become a power worth reckoning in the technological world. However a similarity in these articles that I find slightly confusing, is that neither completely define what Web 2.0 actually is. This makes me believe that Web 2.0 is a technical term for people in the educational framework. Another interesting similarity between these articles is exemplified in the fact that both of their titles are questions. This means that they both are uncertain of the extent to which web 2.0 will help education progress.
Despite the many similarities in these two articles, there are also many differences. The main one being in how the authors believe web 2.0 will change education. The article "Why Web 2.0 is important to higher education?" advocates the use of these social technologies in the classroom. The author believes that Web 2.0 has provided the framework for educators to go back and teach through collaborative methods that will come naturally to students. On the other hand, the article "Web 2.0: A new wave of innovation for Teaching and Learning" is not so enthused by the idea of Web 2.0 revolutionizing education. The author believes that there are too many distractions on the web. Furthermore he believes that the open nature associated with web 2.0 will allow for the propagation of incorrect knowledge. Upon reading these articles I am exited to see whether the Development of Web 2.0 in education will change teaching in a positive or negative way.
