Put publication dates on articles. Put publication dates at the top of articles. Put publication dates in an unambiguous format (that means spelling out the month, avoiding dd-mm-yy, mm-dd-yy and even yyyy-mm-dd) at the top of articles. Beyond that, it would be nice if there was a design convention that made older pages look different. I don't mean "you can tell this page was made in 1996, it has a flashing 'under construction' icon", I mean something more subtle. Perhaps making older pages greyer? Wouldn't work with photos or videos though. Perhaps making just the branding/navigation greyer? But as well as "old", grey also means "disabled".
