"Worst passwords" of 2011

SplashData, a company that makes password management tools, has released a roundup of 2011's "25 worst passwords," gleaned from password-dumps posted by "hackers" (presumably, sources like the Lulzsec Sony password files). I can't locate the actual study and its methodology (are these passwords "worst" because they're the most common, or because they contain the least entropy? Is the sample set representative?) but the list is still informative, and, of course, it can give a warm glow of superiority to those of us with stronger passwords.

Passwords have been a recurring theme this year, and it's becoming increasingly clear (to me, at least), that passwords may be reaching their end-of-life on the Internet.
