Through INF 506, much has been covered about social media, social networking and the notion of creative commons. I personally found the YouTube clips below to be useful for my understanding of SM and CC.
1) Social Media Revolution 3 based on the book Socialnomics by Erik Qualman. This new version was uploaded on June 22, 2011
2) Creative Commons Kiwi
This video by Creative Commons Aotearoa New Zealand explains very simply and effectively the concept of Creative Commons License in a most interesting and fun way.
3) The slideshare titled, “The Conversation: An Introduction to Social Media” by Tactica Interactive Communications and updated for 2009 is very comprehensive and useful for anyone keen to know about social media. Highly recommended.
