Wikinews is a free-content news wiki and a project of the Wikimedia Foundation that works through collaborative journalism. Wikipedia co-founder Jimmy Wales has distinguished Wikinews from Wikipedia by saying, "On Wikinews, each story is to be written as a news story as opposed to an encyclopedia article." Wikinews's neutral point of view policy aims to distinguish it from other citizen journalism efforts such as Indymedia and OhmyNews. In contrast to most Wikimedia Foundation projects, Wikinews allows original work in the form of original reporting and interviews. In contrast to newspapers, Wikinews does not permit op-ed.
