Another mystery of how a story can stay on the front page for hours with one comment while others drop off more quickly with active discussion happening. I know it's been discussed before, but sometimes I'm very confused about the ranking of stories.

Number of comments is not important at all, just number of upvotes.

Stories drop of quickly if they get flagged. It also depends on the amount of competition.
