CNET is doing a special five day report entitled “Taking back the Web”. I just finished reading day two, which is dedicated to wikis. If you are trying to wrap your head around wikis or want to read about some of their applications, go read How wikis are changing our view of the world.
Although initially conceived as a form of communal publishing, the wiki is quickly evolving into a multipurpose interactive phenomenon. As evidenced in the aftermath of Katrina and the Londong bombings a month earlier, wikis can be a life-saving resource that provides real-time collaboration, instant grassroots news and crucial meeting places where none exist in the physical world.
