Also, the question is: Is it interesting to discuss it again? Has something important changed? Is the article so interesting?
When I find a repost with a good discussion, I sometimes put a link to the old discussion with a snippet of the most interesting comments. Sometimes the comments debunk or clarify an important point of the article.
Ok I thought HN was smart enough to re-open comments or something for old stories.
Personally I don't like this workaround. Because we now have several threads for the same article. And tools like Hacker News Sidebar [0] don't work anymore.
But granted for my original question this is probably the way to go.
