Posted by Craig Shepherd on 9/16/09 Overview: Wikipedia is an open-authoring encyclopedia. The purpose of the website is to provide information about any topic to the general public. Content is generated and reviewed for accuracy by the public. Although public documents can include inaccurate information--particularly on hot topics, much of the content is stable. Links to other pages generally function properly, and content is easy to understand. Content: Although maligned by many individuals as a site that promotes inaccurate information, Wikipedia has much educational merit.

Design: The site is well designed.

Several languages are also supported. Modification and revision dates are clearly displayed and the wiki allows you to
