Article about effective uses of social media in education

I really enjoy coming across these kinds of articles about real-world applications of Web 2.0 tools in an educational setting. Lisa Mansfield posts about how instructor Melanie McBride is making use of Social Bookmarking, Wiki's, and other Web 2.0 tools in courses she teaches at Centennial College in Toronto. A great, straightforward example of how these tools can add value to the instructional process! The article can be found here (I came across it because I am subscribed to suite101.com).
