Reddit 個回覆 sorting algorithm 同主題完全唔同
新comment會容易排先,亦會睇正評數,實際上係用統計學嘅Wilson score interval

Conclusion of Reddit’s story ranking
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
