"This paper discusses two main claims made about virtual worlds: first, that people become “immersed” in virtual worlds because of their sensorial realism, and second, because virtual worlds appear to be “places” they can be studied without reference to the lives that their inhabitants live in the actual world. This paper argues against both of these claims by using data from an ethnographic study of knowledge production in World of Warcraft."
