With more than 500 million unique users some claim that Facebook is now the web. Certainly it is one of the main ways our learners (and many faculty and staff) keep in touch with each other. There are many other social media impacting on contemporary medical education including LinkedIn, Biomed Experts, Blogs, Wikis, Rate my Prof/Doc/MD, geotagging, Flickr, YouTube, SlideShare, Second Life, Twitter and Googlewave. This presentation will build on ideas presented in an earlier IAMSE Webcast to consider the many ways that social media are impacting on contemporary health professional education. Issues such as authority and control, net-gen learners, trans-institutional student networks and digital professionalism will be discussed to both orient participants and provide them with better approaches to working in these environments.
