You could use a password scheme for sites you don't really care much about and stronger separate passwords for important and often used sites.
I do this and it works out well and if you use the important sites enough you will and do remember your strong passwords but for the ones you don't you always can reset your password by email which isn't that inconvenient if you think about how often you are accessing the website that you cannot remember your password.
