I find wikipedia the most objective source out there, as far as that is possible. By objective, I don't mean closest to our view of thinking. I mean able to present all sides of an issue. Whenever I read something from a biased source, whether it be left-wing, right-wing, or even libertarian, whether it be pro-alternative medicine or pro-conventional medicince, I often check it against wikipedia. The footnotes make it easy to check the source.
Wikipedia is as free market as you can get. I love wikipedia.
