DuckDuckGo avoids the 'Google' bubble, which happens when the search engine tailors results based on what it thinks you want. Even with engines that do not do this, you still can easily form a bubble by biases in what search terms you use, and in what sources you choose to look at.
This is my problem. I get most of my technology (and recently the NSA stuff) news from HN, some current events from NPR, and then a couple other politics sites I frequent which I'd rather not divulge ;)
I recently stopped watching everyone on MSNBC but Chris Hayes. He has a great show. He's had Greenwald on a couple times in the past few weeks. Also, Democracy Now! is really great. One of the only programs on TV that talks about Wikileaks and Manning on a semi-regular basis.
