I dunno... if there is one group of folks who I believe will have a reason for choosing what they link or don't link with some care, it's folks who make some money blogging. I'd assume there is a reason before assuming the guy is stupid, but I could be wrong.
If only there was a website, maybe one that even sponsored this event, where you could go and type in some words like "president" and "interview" and "youtubers," and they'd just... hand you the video you were looking for.
