But the only post on the recent submissions list that is actually marked "[flagged] is this one. If it's because enough high-karma users are clicking "flag", wouldn't they all show up as "flagged"?
The only explanation I have heard that makes sense is: The [flagged] tag only appears after a certain threshold amount of user-flags, however each user-flag contributes to the down-weight of the story.
So if the [flagged] threshold is 10 user-flags, then 9 people can flag the article, burying it, and then only at the next user-flag, [flagged] shows up in the title.
Of course, nobody but HN staff truly knows if this is how it works.
