Just as an example: I just noticed [a question][1] on Super User that was closed as a duplicate 12 hours after it was asked, but meanwhile has received 20,648 views in about 2.5 years. The [older duplicate][2] was viewed 6,665 times.

If this duplicate would have been deleted, then I guess we would have seen more duplicates posted, and maybe people would not have found their answer at all.

However: I find it odd that not all viewers clicked through to the other question. This might be caused by the answer that was posted to the duplicate, but I'd still be curious what the other answers would be.
