It's a weird feeling reading other people's email. I'm sad to see Wikileaks didn't at least do a quick regex pass to remove the credit cards (yup, found some) and the personal love notes. I'm generally a supporter of Wikileaks, but mass dumps like this aren't responsible and only give more ammunition to their detractors.
Wikileaks is attempting to provide transparency in a world where that doesn't much exist so boo-fucking-hoo if somebody's Mastercard gets leaked in the process.
Mass dumps aren't adding any more "ammunition" for their detractors than some sort of filtered dump would. Detractors don't need much of a reason to dislike what Wikileaks is doing beyond the fact that they've been exposed.
