Best detail about the site: You can change the language. But at least for German, it is no automatic translation. He translated his whole site to multiple languages. wow!
Glad you like that! Yeah I hired 9 translators to translate into 9 languages. If you switch it to Arabic it goes right-to-left. Fun design challenge.
I saw some mistakes in the french version, I switched back to english once I realized it wasn't the original language. It tooked me two paragraphs to notice it. (I'm a native french speaker.) I thought you would like to know that :) !! Great article. Thanks!
