Recently I've been wondering how does everyone keep the content of their site up to date and duplicate free?
We have a large instance with documents in their tens of thousands, with a large bulk of them being over 12 months old. I don't think I would have any sucess if I was to approach a user with 800 pages and say that 50% of their pages needs reviewing because of their age.
Also, how do you handle documents owned by unknown accounts?
