I do disagree with one point: that there would be no correlation between time posted and upvotes if the reddit algorithm were completely fair. If I post a link to r/tipofmytongue asking "What was that low-budget movie that had engineers inventing a time machine in it?" and the first comment correctly tells me I was thinking of Primer, then it'll be highly upvoted. But later commenters won't get to grab that easy karma since it's already answered. There are only so many "great" things to say in response to most posts. Also, if someone posts in a thread after it has dropped off the front page, they'll get fewer upvotes regardless of what the algorithm does.
