Blogs and wikis

InfoWorld: Enterprise collaboration with blogs and wikis: March 28, 2005: By Michelle Delio :
“Blogs and wikis play opposite roles,” says Martin Wattenberg, a researcher on the collaborative user experience team at IBM Watson Research Center. “Blogs are based on an individual voice; a blog is sort of a personal broadcasting system. Wikis, because they give people the chance to edit each other’s words, are designed to blend many voices. Reading a blog is like listening to a diva sing, reading a wiki is like listening to a symphony.”
