As search engines begin to incorporate more and more opinion data into their results, the distinction between fact and opinion may start blurring to the point where, as David Byrne once put it, “facts all come with points of view.”http://www.nytimes.com/2009/08/24/technology/internet/24emotion.html?pagewanted=1&_r=1

I found this interesting, how sentiment can be incorporated into search results for companies, products or ideas, they use an example and I quote "Using Newssift, a search for Wal-Mart reveals that recent sentiment about the company is running positive by a ratio of slightly better than two to one. When that search is refined with the suggested term “Labor Force and Unions,” however, the ratio of positive to negative sentiments drops closer to one to one."
