Nora, I agree that these principles have been around in a training/learning context for a while, but they also need to considered when designing Knowledge Management approaches, especially those involving the use of social media. We know people learn through Pull, but how often have we seen companies attempt to introduce KM through the introduction of blogs (Push), microblogs (95% Push), wikis (Push), and so on. Maybe we need reminding that even in this field, the old principles apply.
