upvoting moves the post higher in the Hot, Active, and Top views.
technical details
the value of upvotes decay logarithmically over time in the Hot and Active views. new posts and comments have quite a bit of an early advantage, and since upvotes decay, popular old posts and new posts are on roughly equal footing in the Hot and Active views.
here is the algorithm, where R is rank, s is score (number of upvotes - downvotes), and t is time since posting in hours
