fred_nada described it way better than I could in this post earlier in the thread: http://news.ycombinator.com/item?id=3511595 http://news.ycombinator.com/item?id=3511595 "Bias" has the obvious meaning here. When searching for a topic on which I am not very well informed, I expect to see informative, authoritative results(which Google /does/ provides), but I don't want references to what my "friends" think on the topic. This becomes worse because in many cases, these "personalised" results are higher than the ones which should be more relevant.
