Again PLEs..

I was just reading Graham Attwell's paper on PLEs and his discussion of the future of PLEs in e-learning. My immediate internal reaction was: "Yes, yes!" I would also direct my attention to using PLEs beyond the boundaries (?) of informal learning, i.e. the potential of having such an environment within institutions... For working adults, isn't the goal to marry informal with formal learning as part of a rich and ongoing learning strategy? The ultimate goal is to connect new knowledge with existing one, building synergy between theory and practice. These social software based tools/services, that are the base of PLEs, have potential of becoming the necessary bridge between these two worlds of learning.
