Read each article objectively. What evidence is there to support each claim? If there is no evidence for the claim or evidence opposite to the claim, toss it out. If it is neither true nor false, that is, if it rejects the basic axioms, again, throw it out. The basic axioms are: (1) Existence exists, (2) Consciousness perceives (i.e. does not create) existence, (3) A is A (an existent is itself). Basically, (1) existence exists regardless of whether or not there is a consciousness to perceive it. (2) Consciousness has to be consciousness of an existent. (3) A thing is what it is regardless of anyone's hopes, fears, or wishes to the contrary. A is A is a concept Ayn Rand concretized from Aristotle. Keep these in mind when reviewing an article, ask yourself the why and the how, and happy reading!

I read every article with a skeptical eye regardless of source.
(But many here will find that no surprise ;^)
Almost every writer has a bias.

A series of blogs and what people I trust post about on various social sites. I don't trust any canned news whether on the TV, in various publications or online in places like CNN. It is too obviously cherry picked and whitewashed. Anything that looks very interesting I google into for more depth and perspectives.

Take a look at the Christian Science Monitor. I don't subscribe to the tenets of Christian Scientists at all, but their publication strives to be as neutral as they can be regarding their reporting. As a result, the stories can be a bit boring, but generally speaking you'll have a fairly good idea as to what actually happened.
