Google Advertising fail:
* I speak English.
* I read English websites
* I search in English
* My browser reports that I prefer English
* I watch English YouTube videos
* I've registered English as my prefered language
YouTube ads are presented in French.
The problem isn't for me, so much the advertiser. As an advertiser I would be very disappointed that my money was being spent sending French messages to English speakers. I'm really confused that Google is identifying the French version of an Ad as more appropriate than the English one.
Big fail for the service.
I blame you for dropping phrases simple enough that I don't need to hit the translate button :)
