Tim Bray, software developer, has submitted a proposal to the Internet Engineering Task Force for the creation of an HTTP error code that denotes when access to a site is denied for legal reasons.

If approved, accessing sites that are censored would return a 451 code which is a more accurate description than what is being used now.  

I like this idea as it shines a spotlight on web censorship and being a fan of Ray Bradbury makes me appreciate the tribute.
