I really don't think that duplicate content was ever a problem for HN. It's just not an issue.

The community has done a very good job of providing links to earlier discussions and has generally accepted that occasional repeats of old content are nothing to get worked up about and may even be desirable.

I agree. Though I'd like something to address duplicate submissions within a small window. Like the double front-page stories of bing's 30% market share...or the double ask-page entries on the new karma-less comments.
