As Stephen Downes puts it, this is "E-Learning 2.0." And what is most fascinating is that it is deeply intertwined with Web 2.0 technologies. Moreover, in the world of e-learning, the closest thing to a social network is a community of practice, where it is characterized by "a shared domain of interest" where "members interact and learn together" and "develop a shared repertoire of resources." But not only is it user-centred and based on collective intelligence, it's also convenient. What better way to learn than in the comfort of my desk, mug of coffee in hand, sitting back, and relaxing to the rhythm of expert opinion?
