My understanding of the article is that this is more about reducing duplication on breaking stories rather than preventing periodic reposting of long tail and evergreen content. That is, the proposal appears focused on the "news" end of the spectrum rather than the "feature" end.

It's a reasonable request but one I tend to disagree with. Funneling all attention on one version of a breaking story reduces nuance and diversity of perspective. It also rewards fastest posting over finding the best content while taking the community out of the calculus of story value. Finally, to me the dispersion of karma awards across multiple submissions is a feature not a bug...karma should tend toward rewarding quality rather than timing where an explicit mechanism is in operation.

Finally, there are occasions where a story is deemed to merit the full attention of the community. The deaths of Steve Jobs and Dennis Ritchie are examples.
