I have about the same sentiment in regard to personal notekeeping, and do in general care about preserving metadata. Many times I have consulted the date when I created a note or, say, an entry in the password manager—or when I last changed it. That may inform my decision on what to do with the note next, or at least allows me to contemplate how much is not done in the passing years and how much is yet to not do. ‘Remember The Milk’ and Evernote make it pretty nice and easy by keeping the dates and some other info. (Though of course there's a gotcha that RTM's Android app forgets to implement the display of this metadata.) Not that I recommend these apps currently, especially Evernote. Well, after migrating to Org-mode I have a persistent itch caused by the fact that Org doesn't have modification times for outline items, and implementing them in Emacs is a pain. That's one downside of not separating the view from the model. But the creation time is easy to add, in case someone wonders. Similarly, I love having the archive of deleted notes and completed todos: once in a while I need to figure out what the hell I did to some particular items, or I change my mind on some edits. And on bulk moving or copying, I like to keep record of what I moved from where. (cough unlike HN ahem.)
