OER Grapevine is meant to be a neutral meeting place for activists in different "Open Educational Resources" projects (a buzzword used in the education community to mean pretty much anything from free download to free license). This is both an opportunity to evangelize free licensing, and a chance to share ideas about technology, policy, and content development.
