This is a follow up post to How Hacker News ranking algorithm works. This time around I will examine how Reddit's default story and comment rankings work. Reddit's algorithms are fairly simple to understand and to implement and in this post I'll dig deeper into them.

Submission time is a very important parameter, generally newer stories will rank higher than older
The first 10 upvotes count as high as the next 100. E.g. a story that has 10 upvotes and a story that has 50 upvotes will have a similar ranking
Controversial stories that get similar amounts of upvotes and downvotes will get a low ranking compared to stories that mainly get upvotes
