> It seems like it would be better just to let the community decide.That's what's happening.
Discouraging discussion of this story may be the best for HN, but it doesn't seem fair to call this a 'community decision' unless the number of flags is comparable to the number of upvotes. If it's not, once the moderators have noticed the flagging, it seems fair to say that the moderators have made a decision that the minority should prevail. Again, this isn't necessarily a bad decision, but once you've reviewed it I think you should own it as informed editorial moderation.
On HN you can think of 'flag' as a semi-technical term with a precise definition.
Sometimes articles are marked as both [flagged] and [dead]. What's the difference in status between the two? I thought flagged meant the article was moved down the list, but I didn't find this one present even when following 'More' to the end. Is 'vouching' something that is possible only on [dead] articles? Does it make sense to view 'vouch' and 'flag' as counteracting each other? Even if it doesn't make the article visible again, it might be nice if it was possible to register a 'no-flag' dissent.
