I am sorry but you all sucked here unless you have a logical explanation of why you didn't specify anywhere here THIS TALK IS IN DUTCH !!
Title, description and everything here point out that this talk has been given in English but when I downloaded the video, get my snacks and soda, I opened up the video. After a few minutes later, as soon as I realized the language this guy speaks is freaking Dutch, I had no other way than visiting this web site and pushing the big, blue button there: http://www.nooooooooooooooo.com/
Hope that someone consider this and put a giant warning nearby the video which says 'This talk is in freaking Dutch !'
