"So George Siemens has lost interest in social media ... I should say from the start that I never bought Connectivism, as it muddles up primitive epistemology, dated social psychology and pedagogy to produce a nexus of thinly connected ideas around an abstract noun. Not for the first time have such vague, unsubstantiated ideas gained currency among educators. For me, the real problem is duplicity. Surely he's thrown out his connectivist baby with the bathwater of abandoned social media."
