Nature makes all articles free (to view)

Interesting move from Nature: All research papers from Nature will be made free to read in a proprietary screen-view format. It can be annotated but not copied, printed or downloaded. Is this open access or public relations? John Wilbanks:
"With access mandates on the march around the world, this appears to be more about getting ahead of the coming reality in scientific publishing. Now that the funders call the tune and the funders want the articles on the web at no charge, these articles are going to be open anyway.”
