PG, how about creating a 'hall of infamy and repetition' list for submissions that seem to find their way onto the site every so often? Once a link makes the list, all new submissions are redirected to a page listing the previous submissions w/ points/comments listed.
Some links like this and the comments that ensue are 'evergreen' material, but by continually being resubmitted at a later date the chance of conversation happening decreases and its time on the homepage shrinks while it creates a sort of broken window effect for those of us who haven't seen it for the first (or 6th) time.
