It has gotten harder to train Google news due to the big uptick in the 300 word reprint practice that is playing out in media recently. Even if you manually block all the major outlets, so many sites reprint their stories that I still end up with Miley Cyrus news in my feed.

How do you do that? The only way I can think is discarding any story I'm not interested in, but how do I say, hey Google Now I liked this article?

+1?

Or how do I say: "this was a really bad article"?
