The Ministry of International Relations has said that Wikileaks will not be blocked in SA. I know Ministers aren't exactly known for their propensity to keep promises, but still... The problems with Wikileaks so far have got nothing to do with our government.
In any case, you can't block what's already been mirrored across half the internet.
Yes, I know what you mean... 90% of it isn't exactly revelatory stuff. One thing is for sure: Do not trust the mainstream media's summaries of the leaks... Spiegel, Guardian, Le Monde, NY Times etc tend to be more worried about silly, superficially embarrasing gaffs by ministers and diplomats.
The important stuff is glossed over.
What's more, just because a diplomat said something, it doesn't mean that it's true. These people aren't exactly appointed based on merit... In most governments, an ambassador's job is a good way of banishing someone who might prove politically embarrasing and/or deletarious to one's own ambitions if they were kept on the domestic political scene. When you're dealing with secret 'diplomatic cables' from America, you shouldn't be surprised if you come into contact with a Sarah Palin worldview...
