Psychology 2.0 is a wiki.

• “wiki” means an internet site where most of the published content is editable by the community of users. The well-known Wikipedia site is also a wiki.
• a wiki is designed with the belief that, if people combine their information on a specific topic, it will be both closer to the truth and more detailed than if a sole specialist had presented the same information
• a wiki has two major functions:
  • displaying the article (see 'View' tab in the top right corner); and
  • making it editable (see 'Edit' tab in the top right corner)
• further features:
  • tracking which user has contributed what comment or elucidation to a specific article (see 'History' tab on the top right corner);
  • collecting the articles in different groups; and
  • comment boxes, chat forums
