To indicate freshness of content, likewise, one can use the doc.lastModified() object. This would not indicate a legal statement, and copyright is already applicable by default through the notice on the main page.
My guess is that the real issue concerns one of usability. A site teeming with copyright notices, disclaimers and terms of use will put users off. Therefore, my suggestion would be for web and content developers to insert a copyright notice with the "©" symbol prepended sparingly and preferably in one place only. If need be, one can use a javascript on the Date() object to have the year inserted and updated automatically.
