Wikileaks got on just fine for years without any front-man, and I believe the first media outlet I saw in the UK to cite Wikileaks was The Guardian, back in early 2007 when Wikileaks was still a Wiki. Also, ironically, the invalidation you speak of works two ways, however unfortunately can often take the form of smear campaigns. I'm not saying that Assange isn't a rapist, as I don't know (and if I were to be honest, I wouldn't be surprised. He seems like a real creep), but that by no means that he isn't VERY good at his job, and hasn't achieved his goals.
