Comments by Mitchell Brown:  The video is descriptive about Open Access but tends to group all publishers together, which is a little misleading but that's not a detraction from the video. arXiv is used as an example of how to a preprint sharing model that works well for high-energy physics and mathematics but the concept may not scale well to all subject areas. American Physical Society (APS) is an example of a reasonable road to wider access.
