re: depends.
What takes some time is when I want to "deep research" something, which involves digging up obscure sources and documents, doing real math on data, and things like that. I'm not inspired to do it very often, and I prefer locating a link to someone that has.
For just standard news, it's pretty easy to find original sources for most news stories, and figure out what they left out to try and make their point. The most classic examples in recent times were the Kay and Duelfer reports on weapons in Iraq. The original documents shed a lot more light than the news stories did.
