The social component of Web 2.0-related services is providing a new open and personal approach to how we expect things to solve problems in our information-driven world. In particular, students' learning needs require open, personal e-learning systems adapted to life-long learning needs in a rapidly changing environment. It therefore shouldn't be surprising that a new wave of ideas centered on pervasive systems has drawn so much attention. This article analyzes current trends in the evolution of e-learning architectures and describes a new architecture that captures the needs of both formal (instructor-led) and informal (student-led) learning environments.
