A Wiki website is a hypertext on steroids. Any user can create or edit any page on the site using a simple web browser, and all information processing is done on the server side. Wiki sites are powerful tools for collaboration in closed work groups, but can also be used for the general public on the open Internet. This paper summarizes the experience from the first nine months of operation of Sweden's biggest Wiki website susning.nu, including its usefulness in non-profit and commercial applications, in hobby and professional, projects, its social and legal aspects, its relation to geographic information systems, subject information gateways, the establishment of a controlled vocabulary, and its implications on learning, free speech, the price of information, licensing, and copyright. Relevant comparisons to similar projects in other countries are also presented.
