Why do people remember passwords? We've had browsers that can remember them for you, password1, etc. for years now. I make up a new password for every single site I have to log into and let the browser remember it.
Mainly because most people log into these sites from more than one computer.
It's imperative for me to recall all of my passwords as I need them both at work and at home. Currently I am rotating between three different passwords but this is an area I am becoming increasingly paranoid over.
use a password keyring! mozilla provides one if you enable master password and sync your profiles between home and work. kwallet, gnome keyring and keepass are other alternatives. i was working on backporting a gaim master password patch to pidgin but haven't had the time to finish it.
if you write down some passwords on paper and put them in your wallet, rc4-encrypt them with a master password and write down the base64 equivalent. there should be plenty of free javascript decoders for base64 and rc4 so you can decode them wherever you can find a browser. (yes this is paranoid, but if people know you keep passwords in your wallet it's trivial to get your pocket picked)
If you have relatively few passwords, use Bruce Schneier's advice and write them on a piece of paper that you keep in your wallet - safe and available.
