The World Wide Web is a misnomer now, as companies like Twitter and Google have adopted implementation of country specific censorship, i.e. Twitter/Google will start implementing mechanisms that will allow them to ban/control content in specific regions.
To start off, Google has already implemented this for Blogger service wherein blogspot.com blogs are being redirected to blogspot.in domain (when accessed from India).
Migrating to localized domains will allow us to continue promoting free expression and responsible publishing while providing greater flexibility in complying with valid removal requests pursuant to local law. By utilizing ccTLDs, content removals can be managed on a per country basis, which will limit their impact to the smallest number of readers. Content removed due to a specific country’s law will only be removed from the relevant ccTLD. [Google Support]
While this may or may not impact SEO of your blog, but keep in mind that for the Google bot, this is still an issue of duplicate content.
“After this change, crawlers will find Blogspot content on many different domains. Hosting duplicate content on different domains can affect search results, but we are making every effort to minimize any negative consequences of hosting Blogspot content on multiple domains. “
So from now onwards, if you visit a blog that does not correspond to your current location as determined by your IP address, the blogspot servers will redirect you to the domain associated with your country, if it’s a supported ccTLD [country-code top level domain].
That is, its not a world wide web, but a country wide web now.
