How big is your notebook? What if you lose it? I keep copies of my KeyPass database in my safe, at my parents house etc...
I use LastPass. Works everywhere - Firefox, Chrome, IE, Opera, Blackberry, Android, etc. Its easy to use, secure and free.
normally I'm just using notepad to keep mine, but I will try this one LOL I never thougt that side is full of space
I write them down at my notebook (both computer and paper) for those general password The important password such as bank account, paypal etc, i keep it in my mind
I don't use any software or addons to do that. I just used MS Excel to save all my passwords. It's much easier to compile and add this way.
