I'd say that it makes the argument that reuse of passwords is more dangerous than simply using poor passwords. After all, it's complexity didn't seem to matter in this case. In fact, one could argue that the only thing a user of a site need concern themselves with is not using the same password in multiple locations. Once that is achieved, I wonder, if the chances of your account being hacked dramatically decrease more than any other safety precaution you can take, apart from simply not having any account.
