Occasionally, I'm impressed.
This is one of the startups with enormous potential that I consider worth watching:
Hypothes.is thinks simple tools can help us all improve the quality of information on the Internet and in the greater world around us. They are building an open platform for the collaborative evaluation of knowledge. It leverages sentence-level critique to enable discussion or note-taking on top of news, blogs, scientific articles, books, terms of service, ballot initiatives, legislation, regulations and more. They build software, push for standards and interoperability and foster community. They are a non-profit organization, funded through the generosity of the Knight, Mellon, Shuttleworth, Sloan and Helmsley Foundations– and through the support of hundreds of individuals like yourself that want to see this idea come to fruition. Their efforts are based on the Annotator project, which they are principal contributors to, and annotation standards for digital documents being developed by the W3C Web Annotation Working Group. They are partnering broadly with developers, publishers, academic institutions, researchers, and individuals to develop a platform for the next generation of read-write Web applications.
