I would agree. I've been a lurker on HN for a couple years and the recent PG post about creating wealth was new to me. It was a wonderful post, old as it may be, and much more useful to me (a developer) than multiple posts about another acquisition.
Can old links be re-posted after a certain period of time passes?
If so, maybe auto-add a prefix, "REPOST: Article Title", for any link that's re-submitted. That way people who've seen it before can ignore clicking on it, while those who haven't seen it will now have the opportunity to read it.
EDIT: BvS already posted a link to a Reddit post with the same idea.
