phranque,

No, I'm pretty sure these links aren't from my sites but a wide range of large websites (PR 7/8).

TheOptimizationIdiot,

Do you think it's worth the effort to redirect (301) these URLs to a newer article? I am asking this because as I said earlier, these 404 URLs have links from large sites.
