Research on the 'ecology' of end user computing would be quite interesting and might inform future products.
Personal anecdote: I put the date in yyyymmdd format in many of my file names for teaching documents so I can order by time easily. Gnome Shell when it first came out had an 'activity journal' feature (like Win XP I recollect) based on the zeitgeist functionality[1] which I found really handy. You could view your history, click a bar (like on wayback machine) and get the docs. A versioning system based on that would be wicked. Alas, this initiative seems to have died.
