Right, so someone trying to brute force the password into the interface is limited by the speed of the program (or any artificial limits it should have built in :)). In fact, just one word with a couple of numbers has the same effect. Don't forget though, you are trusting this password to a site. If they are hacked, what then? Your 2K years turns into minutes or hours.
