That's similar to what we're trying to do with http://grasswire.com, but not so much "articles" as "tweets/videos," and crowdsource fact-checking after the fact.

So, maybe not very much like it at all, but I agree with your original analysis that curation will be king. News/journalism feels very much like the Internet did pre-Google. There has to be some aspect of real-time curation/fact-checking built in IMO. But obviously I'm extremely biased.
