Who voted this thing out of the crib? If you find this article to be fascinating or new, then I hope to god you're not designing any systems I use...

Before I read the article, I thought you were being a jerk... then I read the article.

I didn't really read the article, but the title gave me another idea:

Type your (potential or existing) password into Google. If you get any hits, it's not a good password.

Of course there are exceptions, and just because Google doesn't get any hits doesn't mean it definitely is a good password. But it seems like a decent measure of password security.
