I dont really read news anymore. But i think forbes was a decent one. I havent checked in a while though.

edit: i'd say hackernews is a good way know about things. much variety.

edit2: news is not really that important to begin with. It's just about what's happening in the world. It's not that important to know that. You rather want to fill up your brain with information about engineering, science, nature, etc. You know.. information that you can "USE". That's why it's "useful".
