The Knight New Challenge, in it’s 5th year, is a very cool effort to fund ideas that mashup aspects of the news industry with new tech.  Looking at the winners from the past four years…I think most are more about inspiration than viability, and that’s just fine.  Here’s three that stood out to me…

image Idea is to facilate sharing of documents used as sources in news stories.  I could imagine this idea could grow into community or algorithmic fact checking.
