A wiki is a collaborative project. It can be created for any topic that has an active community of people who are inrerested in it. Do you want to find an interesting quote to use in a writing project or report? Go to Wikiquotes. Do you want to learn the most recent information about a place you're planning to visit? Try Wikitravel. A wiki gives the community a way to gather informationtogether and modify it as things change. Wikis are dramatically changing the way we get information. And unlike information in a printed book, the information is being updated all the time.
