The person in the room who's in control of the flow of Youtube videos. Talented Youtube DJ's who take themselves seriously have to be constantly updated with the most fresh videos around, sense the video's "feel" and "timing" as well as the viewers' "vibe" in order to create a good atmosphere, and the ability to keep up with youtube-DJing for hours.
