Here's the announcement:
As of April 3rd 2012, we will cease to accept submissions to Nature Precedings. Nature Precedings will then be archived, and the archive will be maintained by NPG, while all hosted content will remain freely accessible to all. Looking forward, NPG remains committed to exploring ways to help researchers, funders, and institutions manage data and best practices in data management, and we plan to introduce new services in this area. We have truly valued your contributions as authors and users to Nature Precedings and hope that you will actively participate in this research and development with us."
This comes on the heels of Dr. Joseph Pickrell's first author submission of a preprint. Correlation? Yes. Coincidence? I'll let you decide. In other news the existence and flourishing of arXiv puts a whole different spin on "physics envy." And, just to reiterate, if I post about a paper, and you don't have access email me and I will send you the paper.
