I don't know how well the analogy holds up.  People protect their
keys, because a) if they lose them, they can't get into their house or
business, and b) if they're stolen, somebody else could gain access
and steal expensive items from them.  People are less likely to
protect their sticky notes, because a) nobody is going to steal a
piece of paper, and b) if it does go missing, the IT guy is just one
phone call away, and c) who would want to break into my desktop
anyway? I don't have any trade secrets in there.
