In contrast, the Web 2.0 definition of “knowledge” is collective agreement about a description that may combine facts with other dimensions of human experience, such as opinions, values, and spiritual beliefs. As an illustration, the Wikipedia entry on “social effect of evolutionary theory” wrestles with constructing a point of view that most readers would consider reasonable, accurate, and unbiased without derogating religious precepts some might hold. In contrast to articles in the Encyclopedia Britannica, Wikipedia articles are either undisputed (tacitly considered accurate) or disputed (still resolving through collective argumentation), and Wikipedia articles cover topics that are not central to academic disciplines or to a wide audience (e.g., the cartoon dog Scooby-Doo).
