That is a fascinating aspect – perhaps the dynamics in an open and easily accessible environment such as the blogosphere challenges many of the rather conventional ideas of what learning means. While on the one hand we see the hierarchical relationship between learner and teacher blurred, also the boundaries of learning processes and teaching processes seem to undergo drastic changes. It may enable us to understand how much potential we have been left unused in more traditional settings where learning was more confined to time and space restrictions. The key point now might be to draw a boundary and close the door to virtual flows of ideas coming in at any time 😉
