Never said ranking algorithm. I said, there's a bunch of links (like job postings and YC company PR posts) that get privileged front page status with their own decay algorithms, yet they aren't flagged as "promoted". They're just mixed in as if it's actually relevant news a bunch of people upvoted to the front page. Or how about all that crap that was on scribd back when nobody knew what scribd was? If you think this isn't a manipulated news source then you're high on a metric ton of horseshit.
