"How does a wiki compare to a blog? What are their different uses?
A blog is a time-based, sequential publication usually authored by one person, whereas information on a wiki is assembled and structured by a group of people. A blog is very much an online journal, and a wiki is similar to a whiteboard, except that it records everything that’s written on it, and lets you see the history of revisions.
In education, I see a blog being used to deliver news and updates to a class, and a wiki being used to work on projects, assignments, and notes."
