I just posted a longer comment on your previous post about Assange and Wikileaks. Anyway, just one point about the quote you took from my post.

I forgot to mention the obvious factor — beyond diversity of opinions and international news media — that makes the pragmatic objection I raise even more serious: the existence of the internet. It is now so easy to share information, instantaneously, with the whole world. Previously it may have been possible to contain information leaks even after they had happened. Nowadays that is practically impossible.

Of course, a countervailing pressure, mentioned in your previous post, is created by the existence of the internet: informational overload.
