Absolutely true - the thousands that have signed up for massive, open, online, courses through platforms such as Coursera and edX are examples of people seeking knowledge and forming groups spontaneously, [without being prompted by the institution] using social media platforms. I've just finished a course through Coursera, e-learning and digital cultures and the passion and drive that students have to seek out knowledge, form relationships and make social connections is inspiring. Just check out the Twitter hashtag, #edcmooc to view the conversation which is 'connected, loose and open'. Thanks Harold as always for insightful thoughts and resources.
