Social media hosting/sharing sites can only be effective with learning when guidelines are established for use as an assessment activity for evaluation learning outcomes. Thus, social media polices are a valued part with using this strategy in your own course; this includes addressing integrity, roles, expectations and consequences for compromising the guidelines. I have used blogs and wikis in courses and they were only effective with a firm set of guidelines for professionalism and monitoring of the site as some students wanted to use them a social, personal means of networking.
