Some interesting ideas to ponder from http://www.hyperorg.com/blogger/2009/07/19/transparency-is-the-new-objectivity/
... during a bloggers press conference at the 2004 Democratic National Convention, I asked Pulitzer-prize winning journalist Walter Mears whom he was supporting for president. He replied (paraphrasing!), 'If I tell you, how can you trust what I write?,' to which I replied that if he doesn’t tell us, how can we trust what he blogs?
... What we used to believe because we thought the author was objective we now believe because we can see through the author’s writings to the sources and values that brought her to that position. Transparency gives the reader information by which she can undo some of the unintended effects of the ever-present biases. Transparency brings us to reliability the way objectivity used to.
... credentials and authority work best for vouchsafing commoditized knowledge, the stuff that’s settled and not worth arguing about. At the edges of knowledge — in the analysis and contextualization that journalists nowadays tell us is their real value — we want, need, can have, and expect transparency. Transparency puts within the report itself a way for us to see what assumptions and values may have shaped it, and lets us see the arguments that the report resolved one way and not another. Transparency — the embedded ability to see through the published draft — often gives us more reason to believe a report than the claim of objectivity did."
