The “wiki” and open-source phenomena are transforming the way knowledge is generated and shared around the world. The word wiki is from the Hawaiian term wiki-wiki, which means to do something quickly (1). The term became prominent because of the online encyclopedia Wikipedia (www.wikipedia.org), which now has more than 2 million articles contributed by tens of thousands of people. People in so many fields are using Internet communities that the term wiki has come to refer to an online group that collectively works on a project. In the business world, the wiki concept is called wikinomics (1). Even U.S. spy agencies are using a wiki-like online community, Intellipedia, on which people with U.S. security clearances can update each other on security matters.
