I'll simply defer to Carlson's description of his site, and leave it at that.
Well-l-l-l,... that video clip had already gone "viral" and the hits on YouTube were screaming upward as word spread across the internet. It's been one of the "most-viewed" videos since right after it went up, with a number of viewings up around 300,000 in only a day. I sincerely doubt that count is due to The DC's posting of the video. So my conclusion would be that The DC used the video, not the other way around.
No big deal either way, I'm only commenting on the probabilities.
And in any case, I appreciate your posting the link on FR, since I myself might not have heard about it yesterday otherwise.
Happy Thankgsiving, and hope you enjoy your day.
