I think it was the “you dont learn much alone” comment which I was reacting to in my previous comment, as it seemed to imply that my PLE was not going to be very efective, because it dicounted other people who were engaged in simmilar activity. If we phrase the PLE as a PLN it makes it much clearer that this is a network of like minded individuals, facets of whose activities overlap, and who can aid each other like fellow travelers where this ocurs. For me the primary purpose of my PLE/PLN is to leverage on the experience of others and avoid re-inventing the wheel.
