I suggest that you develop a thicker skin when dealing with feedback. Not everyone thinks what you are doing is helpful or beneficial. I can't speak for Swartz, but his article clearly says that he considered ALL news to be bad and even unhealthy, including your 0.1%. So to claim common ground, or to speak for him, is self-serving.
As for Grasswire, I think your solution to trying to improve the news won't work. As someone who previously ran a collaborative fact-checking site (which included a factcheck watch that monitored the main fact-checking sites), I think fact checking is over-rated. Most people are not really that interested in fact-checking the news, or in even reading fact checks. Fact checks themselves are in most cases just as biased as the reports they claim to fact check.
Nonetheless, I am genuinely interested to see how it works out for you.
