I don't know about you - but I have never seen a Youtube overlay ad that I wanted to click on. The topics are often completely unrelated to the video - annnnd - I'm watching a video damn it - why I am going to click on this in the middle of my watching?

YouTube will be forced to start running 10-15 second post-roll video based "commercials". Mark my words - it's coming - and while it will be annoying for most of us, it will be much more effective from an advertising standpoint.
