This document discusses a cloud-based Personal Learning Environment & Network (PLE&N) created by Professor Eric Tsui for lifelong peer-based learning. The PLE&N allows teachers, students, graduates, and guests to collaborate using Google tools like Feedly and Google+. It provides a platform for knowledge and experience sharing between participants from different backgrounds. Some key benefits of the PLE&N include supporting a co-learning environment, accessing expertise, collaboratively managing information overload, and facilitating lifelong learning beyond a single course or term. However, maintaining trust and quality of discussions is important for the PLE&N's success.
