Answer to Question 2
The online encyclopedia called Wikipedia is the best-known publicly accessible wiki. With millions of articles contributed by volunteers around the world, the nonprofit Wikipedia is the most popular general-purpose reference work on the net. People can update any of the existing articles with current information. Critics point to problems with accuracy and bias, exacerbated by the site's open structure that allows anyone promoting an agenda to edit articles. Corporations and government agencies are known to quietly edit entries about themselves to put out the best spin wherever possible. Occasionally, the site blocks people from changing an article, especially when it deals with controversial current events.
