Whose Knowledge?
If blogs create new opportunities for expressing voice, then wikis create new opportunities for sharing and producing knowledge. Wikis are simply Web sites that any visitor can contribute to or edit (Richardson, 2006). They thus help fulfill the original version of Web inventor Berners-Lee (1999), who sought to create a tool that allowed the average user not just to access information, but to create and publish it as well. Though there is no authoritative listing or account of the number of Wikis, they are surely far fewer than blogs. They have been principally established so that groups of people can contribute their knowledge and writing skills to collaboratively create informational documents. For example, some of the largest wikis (based on statistics from S23, 2007) include Richdex (an open source directory on a wide range of topics), Wow Wiki (an information source about the World of Warcraft online game), and wiki How (a collaborative how-to manual)
