Re: The commentary portion, I agree, there was no benefit to either Wikileaks, or society. Most of the release was just gossip, and you can bet the diplomats of all the nations involved have similar commentary for the others they deal with. I'd love to see a comparison of China's private communications regarding North Korea. The difference being, I'd not put much stock in the life of the 'leaker' in that scenario. When the final blame is laid/verified on the current 'Leaker', at best, he'll have a chance to reflect on the wisdom of his actions while Julian gets rich and famous (warranted or not)
If it happens once, it's a bug. If it happens twice, it's a feature. If it happens more than twice, it's a design philosophy.
