I'd lean towards saying this is more a great way to start getting views. I actually used Project Wondeful on a webcomic (need to get back to that...) and it did bring up views, though fewer stayed than came the first time. I did STILL retain readers I wouldn't have gotten originally without the ads (at least until I got so busy it went into hiatus). I agree with Marc Corn though, you need content too. It's one thing to put butts in the seat... another to keep them. Granted, I'm speaking from a webcomic standpoint, instead of videos, but I think the concept is probobly the same.
