Lastly, being more clear with URL makes it easier for curious minds to find that which we too often stumble across anyway.

The intent is honorable, but the US doesn't own the Internet and try as they might, can not control URL's in other countries (yet).

As CNN reported a few days ago, the majority of kiddie-porn sites are on servers in the U.S. The americans, with the help of the UN can't find Bin Laden - how do they expect to control the 'Net with a few words on paper?
