Generally good - we have a right to know if torture is on-going, or why wars were truly declared. The diplomatic cables were a bit of a joke, though.
My criticism is in Wikileak's organisation; it is not an organisation free from bias. It has an agenda. Many on the radical Left have embraced Assange as the latest subject of their puerile hero-worship when he retains a tremendous amount of heirarchal control over both the organisation itself and the information leaked - his politics are on record in the Forbes interview as Minimalism or Marketism. Wikileaks is part of 'the media' and subject to many of the same constraints and flaws.
Having said that, I do consider Assange to be a trustworthy, if tremendously narcissistic, human being.
