I don't have a keywords I look for, but I do have the opposite - a blacklist of words I block in my RSS reader for news sites. I only add word when it became obsession (by news sites, not by me) to a point that there are no longer news but only the topics the news are obsessed with. I read news to get, you know, news, not something that was beaten to death hundredths of times. So here's the blacklist:
