I use strong unique passwords for any site that could cost me anything if hacked, like bank access (c 10 characters from 96 char set). For sites that no sane person would want to hack, like tech blogs, I use a simple common password.
And what is the point of changing passwords? If a password is sniffed, your bank account will be cleaned out before you realise it. The only other issue is if your computer is stolen. Then there is a chance that someone will try a brute force attack. So (hopefully) this risk can be minimised by bios and logon passwords. Also if my computer was stolen, I would notify the bank immediately and change passwords. A password safe is handy particularly if it requires approval to copy a password/user name to the clipboard. I hope people will respond to this and prove me wrong.
