I don't have any problem remembering them personally (then again, I still remember root passwords I used when I was thirteen and they were completely random characters).
Sites like HN and Reddit I'm happy to use the same password (I'd be minorly annoyed, but realistically I wouldn't be that fussed if I lost control of either account, I can either recover it or even create a new one), but any site where someone finding my password could cause a problem has its own password, and I can remember them all.
Occasionally I forget which password goes with which site, but not often - actually I find it harder to remember which username/email goes with each site.

So very true. My password creation process is fairly memorable, and tends to meet the requirements of any site (password length, numbers, capitals etc). But user names - it's an email address, it's the name on your email address, they do accept spaces, they don't accept spaces, they only have 8 characters ... drives me mad !
