I think that most people on here haven't considered this. In fact, I arrived at your comment by searching the page for "reset". The majority of folks seem too focused on trying to outclass Justin and/or getting in the last word. They're not thinking. Just for fun, I went to see how many licks it actually does take to get to the center of a tootsie roll pop i.e., clicks to reveal a password using the passwords dialog box in Chrome? There are about 27 keyboard button presses for the URL, then a mouse click for the Show button. Fair enough. Too bad I can get to the password reset field in Facebook in 3 mouse clicks, using my bookmarks bar. I'm pretty sure that I won't need 25 more clicks for the verification email. So if we're all just gauging security by how difficult you can make getting at a password, then I beat Justin. And my "exploit" is platform independent.
Someone who can access your computer, unlocked, can login to your Facebook account (the password is saved), change the password, verify the email, re-save the new password, and it's just as easily "game over". You would never know what happened. Justin is absolutely right. His group is doing users a service by making these things more transparent. Folks who make exceptions based on this "security through obscurity" model should not be security tech leads.
