A couple of links: figshare is a site where scientists can share data sets/figures/code. One of the goals is to encourage researchers to share negative results as well. I think this is a great idea - I often find negative results and this could be a place to put them. It also uses a tagging system, like Flickr. I think this is a great idea for scientific research discovery. They give you unlimited public space and 1GB of private space.
