On: Facebook Has Begun to Rank News Organizations by Trust, Zuckerberg Says

That might be because there is more than one person the internet, and people sometimes disagree.

And Facebook doesn't need to do the choosing; they could use a mix of independent, non-partisan rankings of news sources (example: http://www.allgeneralizationsarefalse.com/the-chart-version-...).

To be clear, I don't think they'll do that, but they could.
