Ethan Zuckerman has an important post about the growing global governmental blocking of online content, discussing recent blog-blocking by India:

He writes:

That India is blocking any sites is disappointing. I’d like to see all governments - my own included - block only as an absolute last resort, and as a way to prevent access to content that’s clearly illegal, like child pornography. And I think it’s critical that governments who do block the Internet do so in a way that’s transparent, posting a page that makes it clear that a site has been blocked, offering an appeals process and makng it clear that the page isn’t inaccessible due to technical errors.... blocking blogs is a slippery slope. Blocking opaquely makes it even more slippery.
