Mention wikis, and most folk think instantly of Wikipedia, the controversial but undeniably popular and successful online user-built encyclopedia. However, the wiki model has a great deal of potential for other smaller group-collaboration projects, enabling the group to edit an online document without needing web authoring skills (and without having to bother their sysadmin too often). It seems that the business world is starting to wake up to wikis as a way of emptying their email inboxes of tedious back-and-forth, and once the commercial sector gets a whiff of a time-saving technology you can expect big take-up and development to follow.
