CodeIgniter Multi-Language, Multi-Version

Usually SEO guys prefer URI languages..

Personally, I think I'm done with that. Our sites shouldn't be built for robots, robots should be improved.
The more unnecessary info in the url, the uglier it looks.
I'm ok with meaningful urls though, like /ci-multi-language, because with that the user can tell what the link is about before clicking on it.
