Wikileaks has been influential and might become more so with further disclosures announced, one of them relating to a big US bank.
Whether it's a good thing or a bad thing I really can't judge - is it correct for war secrets to be leaked? Because times of war do receive special treatment because subversive and coercive means would be used at those times.
However, Wikileaks is a whistle blowers delight. Big entities can and do hold the world shielded from reality at times... If China is growing concerned about NKorea, it better announce it to the world and not lie like it did some time ago.
Analogy: The way governments are chasing Wikileaks to shut it down is the same as China censoring information and punishing 'perpetrators'. Isn't it sad that people don't care about Wikileaks as much as they do about, let's say Justin Bieber or God? (Poor pair to put together I know...)
But Wikileaks stands for transparency and accountability - may be we should stand by it.
