This presentation on The OER FLOW and Social Media was animated by Alexandra Okada and Scott Leslie. The former Skyped in from the UK. The presentation was audio streamed at http://bit.ly/opened-c485.
A primary reference was Collaborative Learning 2.0. An overview of this book is available at http://www.openscout.net/news/105-collaborative-learning-20-open-educational-resources. Ironically, there is no e-book version available. It is available from Chapters for $190 or $165 at Amazon.ca. The nearest one in a library is over 100o miles away from me.
