I wrote a post about security a few days ago and I wanted to follow that up with an article I read today from The Washington Post. It's a quick read but does a good job at humanizing the debate about digital security. I can definitely appreciate Schmidt's comments about "breaking the internet" and have no problem believing that countries will at some point want to create their own version of the internet (some are already trying to do so). Iran might eliminate Israel from any of the searches done from within their country, quite literally wiping them off the map or Russia and China might try to whitewash the internet and close it off completely from outsiders.
This obviously becomes difficult to do this as instant global communication services like Twitter continue to grow in users but it's naive to think that government's around the world are not already scheming up ways to create a closed internet.
