Hypothes.is – The Internet Peer-Reviewed
http://hypothes.is/

They think relatively simple tools can help to improve the quality of information on the Internet, and by extension in the greater world around us. Hypothes.is will be a distributed, open-source platform for the collaborative evaluation of information. It will enable sentence-level critique of written words combined with a sophisticated yet easy-to-use model of community peer-review. It will work as an overlay on top of any stable content, including news, blogs, scientific articles, books, terms of service, ballot initiatives, legislation and regulations, software code and more-without requiring participation of the underlying site. It is based on a new draft standard for annotating digital documents currently being developed by the Open Annotation Collaboration, a consortium that includes the Internet Archive, NISO (National Information Standards Organization), O’Reilly Books, Amazon, Barnes and Noble, and a number of academic institutions. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
