I have long questioned the bias, intentional or otherwise, of search engines. It irks me that Google so frequently claims their algorithm is objective, when most information we generate is subjective, despite our best intentions. I have little doubt that Google intends to be objective, but so probably does Dan Rather.
A recent article from USC explores how an algorithm can be more biased than human editors, and the folks at Search Engine Watch weigh in as well. I hope the notion that algorithms are not inherently objective continues to catch on.
