For stories that have been posted on sites that are no longer running, I think it would be a good idea to be posted again.
But if you can still access them at any given time. I´ll also have to say ´what´s the point´? I don`t want to read the same story on three different sites. And for the comments, if you really want to give/receive a comment there is always a way.
Just my two cents.
