I was glad you raised the question, as I had the same thought as you at first. That just cutting and pasting some documents is not journalism.
I then read a tonne of definitions of the word "journalism" and to me. They pretty much all just say journalism is getting the facts out there, in any form. There's no requirement for a journalist to make a "report", for it to be journalism.
I would be interested to see more examples of journalism where no report was written.
I'm not objecting to Wikileaks, I'm objecting to Assange calling it journalism.
I've gotten downvoted simply because people are emotional over this -- as if I'm attacking them.
