The key difference between a blog and a Wiki lies in how information gets added and updated. On blogs, content is usually published by one (sometimes two or more) authors who have access to the blog’s dashboard. With a Wiki, on the other hand, content can be added, modified, or deleted by a wide variety of authorized users. In other words, blogs are editorial, whereas Wikis are collaborative. In addition, whereas content on a blog is displayed in reverse chronological order, the content on Wikis is accessed through search. This site where you are reading this article is an example of a blog, while Wikipedia is an example of a Wiki.
