Blogs vs Wikis, How Similar are They?

Blogs and wikis are so similar, and yet so different. Both are webpages that relay information from one person to another, both are dependent on the World Wide Web and both require authors to update information on a regular basis. The question I am trying to answer is which one of these two forms of webpages can  give readers more qualitative information, and which one can draw more attention from readers.  The way I will approach this problem is to first fully understand the differences between these two type of webpages, then I will draw up the cons and pros of both, and lastly I will pick a winner that gives more qualitative information base on my observation.
