I'm surprised the channel hasn't had 1 billion views before this promotion. But I guess if they really want the views now this campaign can help motivate fans into watching a lot more (I generally prefer to watch the clips on sesamestreet.org, but you can't comment on the clips there).
I've been watching as much as I can, often going through playlists (If I want to do something else I can let the playlist run and it counts the views), and it does get tiring. Even when I just click on certain clips and let them play for a few seconds before clicking on another clip it gets tiring.
It would be great if a few more special things came out of this besides the secret video. It'd be great if Sesame Workshop were to reward fans by uploading some of the rarest most-requested holy grails and characters. I doubt they'd add "Lucy in the Sky with Diamonds" or any other rare song cover, but it'd be great if they'd add videos with Leslie Mostly, Deena and Pearl, The Mudman, Shivers the Penguin, Aristotle, and Warren Wolf, the rare "Surprise!" song with the cast (not to mention the one with the hippy Anything Muppets), the fabled "crack in the wall" monster cartoon (I believe it exists, but am not sure if I've seen any official enough sources for it), and others.
