Since you have stopped allowing commenting on news articles, instead you should allow readers to simply rate the article without comments.
Yahoo, you should be in touch with what readers think of your articles. If you don't want commenting, you should at least allow readers to give you their opinions on the accuracy or quality of the articles. You could have several kinds of opinion categories, or just let readers send you comments that are for your info only. Just so you know how people are reacting to your news articles. I see some good ones, and some really dumb ones. I'd think you'd want to know how you're doing.
