The building blocks provided by the Open Educational Resources movement, along with e-Science and e-Humanities and the resources of the Web 2.0, are creating the conditions for the emergence of new kinds of open participatory learning ecosystems that will support active, passion-based learning: Learning 2.0. This new form of learning begins with the knowledge and practices acquired in school but is equally suited for continuous, lifelong learning that extends beyond formal schooling. A new approach to learning is needed---one characterized by a "demand-pull" rather than the traditional "supply-push" mode of building up an inventory of knowledge in students' heads. Demand-pull learning shifts the focus to enabling participation in flows of action, where the focus is both on "learning to be" through enculturation into a practice as well as on collateral learning.
