wiki+versus+blog

=Wikis or Blogs=

**W** **hat is the difference between a wiki and a blog?**

A __**blog, or web log**__, shares writing and multimedia content in the form of __**“posts”**__ (starting point entries) and “comments” (responses to the posts). While commenting, and even posting, are open to the members of the blog or the general public, no one is able to change a comment or post made by another. The **__usual format is post-comment-comment-comment__**, and so on. For this reason, blogs are often the vehicle of choice to express individual opinions. A __**wiki**__ has a __**far more open structure and allows others to change what one person has written**__. This openness may trump individual opinion with group consensus.
