Honestly, Assange shouldn't have been the face behind the leaks. It should've been the agency's "face", and it should've been dumped all at once, like most of their past releases.
Also, think of the political dynamic. There isn't much difference between one huge scandal and ten - there's still only so much airtime. Anything leaked as a unit can be responded to as a unit.
Anyone could anonymously create a torrent and paste it in some related thread, the important thing, and why people go to Wikileaks, is getting it read faster than "they" can delete it.
One look at Assange's Twitter is all it takes to see the obvious anti-Hillary bias. The shrill "Hillary's got an earpiece!" post is one of the most glaring examples.
Perhaps you can provide more info on exactly what documents you think Putin is not happy about?
I had mixed feeling about Wikileaks before (as I think anyone should, since it's a very complex topic), but any thoughts I had as to him be impartial in any way (as a good journalist should be) are now out the window.
