So what? Seriously, why does it matter even one iota if there are others doing the same thing? Your entire objection to Wikileaks seems to be that it is unconventional in a literal sense, it doesn't follow the conventions of journalism that you are comfortable with. But that's just how new things work, they're different because they're new and innovative.

Unless you have a better reason than "it's different and weird", your objections are just like those of a grumpy old man complaining about the music the youngsters listen to these days.
