Well, what's ironic, is that I read the Guardian, amongst other newspapers.
I personally find it helpful, when a newspaper from a country that is not my own, is linked-to on HN, what political leanings it has, as that helps understand the story and provide some background, and in some cases the particular views of a journalist.
I like balance, or at least reading stories with views I may not necessarily agree with, but at least I make the effort to read those. And perhaps I'll learn something, or change my views on a topic.
