I am not an admin, I only need to remember my passwords. Personally, I have a less-secure "story" and a more-secure "story". So I basically have 2 variations on the story behind my passwords. That doesn't mean I have only 2 passwords of course. So even if someone cracked one of my passwords they would be able to guess my others. And I have been using the secure scheme since 1996. The password looks totally random, but I know the story behind it, and remember the variations I made. So I can write down a single letter (or number) and know what the password is.
I think my point is that people need to THINK about their passwords, and make it unguessable yet something they can write down reminders for without compromising the guessability. Now making it 'uncrackable' is a different story completely.
