What is the Purpose of a SharePoint?

A SharePoint site is a web site that provides a central storage and collaboration space for documents, information, and ideas. Your site is a great tool for collaboration, just like a telephone is a tool for communication, or a meeting is a tool for decision making. This site is dynamic and interactive; members of the site can contribute their own ideas and content as well as comment on or contribute to other people’s content. They don't have to use a complicated Web publishing process before they can post a document or make an announcement.
