Ask HN: Is there a news startup for collating sources?

With the Prism story there was a hugely complexity of sources. Different news services had obtained information from both government insiders and the companies. There were also lots of direct primary source like companies or employees putting out statements.

Because of the complexity and the fact the sources were all over the place it made it close to impossible for anyone to stay on-top of the story fully.

It seems like in the future this will happen more often (for example stories breaking with live reporting on twitter) so we need a better way to track primary sources.

Is there a startup working on this ?
