I found the following video on YouTube (of course). Since this is a highly-charged political year, I thought this might be an entertaining diversion. When it comes to providing content online for students, particularly when using a Web 2.0 technology such as a blog or a wiki, instructors have to weigh the benefits of each technology before implementation. Both wikis and blogs have their uses and the instructor should have a good understanding of what each technology is and what each is best suited for.
Enjoy!
