No. That does not happen. I worked on it. If you read all the articles, all of them tell the exact same story. Trends are detected, and then approved to go into a candidate set to be algorithmically ranked for each person. As part of approval, the curators write the headline, snippet, and choose the top article on the results page according to a standard that insists on an unbiased widely recognized news source. The accusation of bias boils down to, "I wanted to link to Breitbart, but that's not unbiased source, so I had to link to the AP." Well call the whambulance! You can't link to alternet either.
