Ask HN: How many times will the shoelace story be submitted?

Over the past day or so I've seen this story submitted many, many times. Mods - I know that some great stories slip through the net, so you now allow resubmission under some limited circumstances, but please can we have some way of correlating associated stories?

There are several other examples of this as well. I know that automatically identifying related stories is hard, but your audience can do it if you provide them with a simple interface.

This is a great story, but maybe we don't need 10 (and counting) submissions.
