I note that Nature have announced Precedings:
Nature Precedings is a place for researchers to share pre-publication research, unpublished manuscripts, presentations, posters, white papers, technical papers, supplementary findings, and other scientific documents. Submissions are screened by our professional curation team for relevance and quality, but are not subjected to peer review. We welcome high-quality contributions from biology, medicine (except clinical trials), chemistry and the earth sciences.
Interesting. As one might expect, blog reaction is mixed... for example, the positive reception by David Weinberger draws some negative comment from those on the institutional repository side of the fence, who argue that repositories (despite the fact that they are largely empty!) already do all of this.
The announcement of Precedings echoes almost exactly the point I was trying to make in my talk at the JISC Repositories Conference and in subsequent posts - we need to stop thinking institutionally and instead develop or use naturally compelling services, such as Precedings, that position researchers directly in a globally social context.
Of course, it remains to be seen whether Nature have got Precedings right, but I think it is an interesting development that deserves close attention as it grows.
