Facebook has been accused as being left wing... no really, it has. Apparently they filter out more conservative news in favour of progressive sites and journalists. As a progressive, I'm not that worried about this. And as a reader, listener, watcher of news, I'm not at all shocked or surprised.
The fact is, there is no such thing as impartial news. Everything is put through a human filter, and that filter exposes the views of the human who decides what makes the cut for 'news' every day.
This is why I like to consume a variety of media every day from 5Live, to the Metro, the Guardian, the FT, the Times, and the BBC. This way I get a range of views and can make up my own mind.
The rise of Facebook as a dominant player in news has already worried some media watchers who are concerned the social network could become too powerful and set the news agenda and potentially block news that might not fit its corporate agenda.
