"a mixture between the blog and the wiki, in which articles are posted on a journal in date order, but remain editable by other users." (From Tonkin, E 'Making the case for a wiki'.)
A Bliki (also known as a WikiLog, Wog, WikiWeblog, Wikiblog, or Bloki), is a blog with wiki support. This means that after (or before) an article is posted to the blog, it can be edited, either by anyone or by some group of authorized users.
