>Crowd-sourcing news quality does not work. There's no ground truth.
This is not exactly true. At my site, newslines, we crowdsource news by collecting and summarizing only the factual parts of each story. While Google News aggregates articles, we select the factual information from them. In effect we put the factual data from long-form news articles into a database. Even if you have highly partisan sources you can still extract factual information. A good example of this is our newsline for Emma Sulkowicz, the so-called "Mattress girl" [1]. In her case, the news sources are extremely partisan, but even so we can still extract factual information to create an unbiased view of the news. We belive our solution is far better than Wikipedia for both handling of news events, and the elimination of bias.
We are currently looking for contributors for other lines, particularity Donald Trump.
