I endorse the serious note - I have a key layout I use for throwaway passwords based on taking an initial character from the website name, which is quick and easy to type on keyboards (but admittedly hard on iPhone). Eg I went back to confused.com (insurance comparison site) recently after a year and got in with a couple of guesses.

Emphasise throwaway passwords though - I use XKCD method for anything that gives control over other stuff (Gmail especially) but it takes some cognitive load off the unimportant stuff while still protecting against password leaks.
