Giancarlo Ditrapano in an interview with Casey Neistat (aforementioned) regarding advertising on his very popular YouTube channel:
In April, YouTube began allowing all of its the users the option of earning ad revenue from their uploads, a seemingly ideal situation for a guy like Neistat, who self-finances the vast majority of his films and has already logged more than 18 million views. But Neistat refuses to monetize his channel despite the fact that he could seriously inflate his bank account with just a couple of clicks. Those horribly annoying ads are obstacles between the work and the audience, he says, and that gets in the way of what he wants to do.
Even people that make ads don't like ads. It is a great interview.
