Apparently in the algorithm time is a multiplier that increases the "gravity" but when the first post everyone saw here a few days ago has 1000 upvotes and everything else has 20-30~ even with the multiplier it stays on top. Those posts were an exception to the normal traffic that beat the algorithm. Maybe if the algorithm was based off of like "if x% above the average post karma for that instance then it gets a bigger time multiplier to increase its gravity over time"

But I think those posts getting upvoted hard-core beat the algorithm and it's going to take forever for them to fall.
