Google will always send cookies and know the IPs. IPs will pinpoint from where you contribute contents to WordPress Blog Host.
There is no need for WordPress to specify a blog belongs to which nationality. Because in a blog, it's not a normal/traditional media. And participants from all over the world blog, and nationality becomes unnecessary. Google as a search engine will and should place these blogs under USA, and USA jurisdiction because those contents serve the host's interest. In fact, if any of our blog is deemed undesireable, it is not us who will act but WordPress from USA.
So you see, if you want to be blogging under Belgium, you can go to a Belgium blog host. Or you can ask wordpress to start a host in Belgium itself. If WordPress start letting blog divided into nationalities for Googles... it's not only Googles that will 'help' you. Government, powerful entities and so on will come in the name of their nationalities after WordPress.
That's how Yahoo China was fighting a loose game with Baidu. Yahoo China simply got into too much 'adjustments', so I heard. People will say... "Wordpress China? China must control what... ... Because it reflects China!"
You got the drift? That's the number problem about blog host. Because blogs are unprofessional, and many governments especially Asian's don't understand blogs at all beyond their suspicious eyes on their impact of self expression. Look at my blog. Damn~ It is a clear cut consumer case, and that ERC threaten to take legal action citing a Singapore lawfirm.
In IT, I may not be as good as most... But in this, I must warn you guys and gals... It's going to be a potentially very big bad move.
If WordPress do so, kindly inform us, especially those Asia.
If you have WordPress Blog Myanmar, know that Myanmar government may be so zealous on WordPress... Do you want such attention???
"Myanmar what?! That Myanmar side of WordPress blogs support monks! We must do something on WordPress!!!"
Better stay clear. We are bloggers. And that's why divided into languages, but don't label nationalities. You never know which government will be so excited... ... Government have IT experts, including hackers. And politics can be very dirty.
Scope meant well.
