I have consolidated the languages taxonomy on wordpress.tv to now use the native language name and script, rather than English naming. As you can see, this cleans up the widget on the WordCamp.tv page quite a bit:
For those that are curious, here is the list of English names, and what they were changed to:
Arabic – اللغة العربية
Bulgarian – български език
Czech – čeština
Danish – Dansk
German – Deutsch
French – Français
Dutch – Nederlands
Italian – Italiano
Hebrew – עברית
Japanese – 日本語
Norwegian – Norsk
Portuguese – Português
Romanian – Română
Spanish – Español
Russian – Русский
Slovak – Slovenčina
Swedish – Svensk
