Comparision between KM and PKN
Content-based process is regarded as a major factor which leads to Knowledge Management's incompatibility in current situation. In contrast, user-based process focuses on each individual in a learning process. That makes the driving force of knowledge shift from content database of organizations to learner(users) themselves. Furthermore, comparing with data or information, knowledge can only be evaluated or managed by individuals, which implies its identical feature.
 * Content-centric vs User-centric

In PKN model, knowledge learning is undertaken with a high consideration of its natural feature - distributed format. In comparison, centralised feature has been proved to perform well in guiding a organized and structural learning session. But the well-formatted guidance could hardly satisfy the various and timely requirements from nowadays users.
 * Centralised vs Distributed

Top-down models and hierarchical controlled structures are the enemies of innovation. In general, learners and knowledge workers love to learn but they hate not to be given the freedom to decide how they learn and work (Cross,2003). For this fact, a better way in coping with this system is to let them develop and emerge naturally, in a freeform way, which could be abstracted to a bottom-up structure.
