Hmmm. It works at a certain grade I think....
With my latest clip I stuffed 3 iframes which played the video (muted) in the background of a page which got ~2k visitors a day. But so far I got only about 300 views out of this 2k visitors instead of 3 x 2k ~= 6k views.
Seems like youtube has a kind of "cut off"....or the traffic is crap and don't stay long enough on my page to count as "view" of the clip....
