Off topic: I am legit interested to know how paywall sites get to the front page of HN. I wouldn't have guessed that the WSJ has a team of people to upvote their content to the front page, but now I'm second guessing that assumption. Or, does HN have some hidden allegiance with certain news agencies that lets paywall content through? Obviously TechCrunch gets in free, since it's used for YCombinator startup advertising, but the WSJ surprises me.
