Thanks, Haim_Ben_Shimon_3JFB and Spiraling Leopard for your input.
The other question that comes to mind is how frequently does ZooTube doctor the video view count on a given video, in order to inflate or deflate the popularity level of a video? I recall Chaim once mentioning that one of the JTF videos had a much lower viewer count than the actual number of viewers who came to the video.
