The concepts of Personal Learning Environment and Social Learning; while seemingly opposite; do appear to be different sides of the same coin so to say; i.e. without resources provided by social learning, personal learning would not be possible; and artifacts produced by personal learning are in turn contributed to social learning resources.
"Personal Learning Environments are systems that help learners take control of and manage their own learning. This includes providing support for learners to • set their own learning goals • manage their learning; managing both content and process • communicate with others in the process of learning and thereby achieve learning goals. wiki
