Rather than integrating it with Google News, I’d say build it on top of a Feedster.com-like service. Not only could 10×10 do what they’re doing with thousands of big media news sources (ala Rubel’s comments about integrating with Google News), they could also analyze sentiment (in a local search friendly way!) by analyzing blog meta data.
It’s a shame that the Newspaper industry doesn’t culturally embrace the very medium that will define its future. If they did, they’d have some R&D propeller heads (and biz folks) working on this kind of stuff.
