The issue of re-submissions comes up repeatedly. I flag them in part because I'm working (in a desultory fashion) on something I think will improve the situation and commenting on the duplications makes them easier for me to find later for my experiments, in part because sometimes the earlier submissions had useful commentary that's worth reading rather than repeating, and in part because it raises awareness of the problem.
Here's one suggestion I made for at least identifying some duplications: http://news.ycombinator.com/item?id=1012215
Like you, I believe that some things are worth seeing again, but as such I think it would be better to have a library of well-regarded and well-respected articles for people to browse. To me, they don't really belong on HN, and I, personally, would like to see the problem/situation dealt with cleanly as an issue of "separation of concerns."
But I'm probably in a minority of 1, so I trundle away in the darkness. At least it keeps me busy.
