The worst passwords of 2011 (list)

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). The actual study and its methodology can not be located (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.
