Related to cracking with a GPU: https://passfault.appspot.com/password_strength.html https://passfault.appspot.com/password_strength.html can measure password strength based on length of time it would take to crack from known patterns and cost of hardware employed to do so. And this, of course, excludes that passwords are often re-used on multiple sites and the risk that your password is already in someone else's database. What this really highlights is that, like fingerprints, it's a lot easier to accidentally share things that can uniquely or partially identify you than to cover up and stay anonymous. (Or find a nice middle ground, pretending to be someone else, say.) There's a lot of security through obscurity that we tend to trust -- that people won't investigate my identity simply because they've no reason to. And so it's worrisome when you see it happen to others.
