Web 2.0 sites allow users to interact and collaborate by creating content in the site’s community. Web 2.0 allows users to do more than just retrieve information like with the Web 1.0 sites. Without realizing it, most people use Web 2.0 sites every day, whether it be through social networking sites, blogs or Wikipedia pages, just to name a few. The idea of Wikipedia is very progressive. It allows for anyone to claim the title editor, which in hindsight might not have been the best idea because those “editors” can sometimes pass off false information as truth. Wikipedia also provides a convergence point for experts of all kinds. In this Web 2.0 world, a man who knows all things Star Wars can have the same power in that “field” as the astrophysicist in his.
