Ability to re-share a previously submitted link

Here's an idea, rather than telling the user that the link they are trying to submit has already been submitted in the past, we could just take that previous link and push it to the front.

X submitted link L (two months ago)
Z tries to submit same link L (today)
L still shows that it's been submitted by X, but gets pushed to the front of all links, as if it was newly submitted.

So basically, Z just updated the date of the submission.

What do you think? We could keep a record of how many times a links gets pushed to the front, and that would give us an idea about the popularity or usefulness of that link as well.

Yeah, seems like a good idea.
