I like this idea in theory AND I recognize that it could lead some people to have a negative experience on the SLR site.
However, my understanding is that the producers use the "favorite" button as a way to determine user desires--I don't like this because that means if I want to encourage a certain type of video, I need to put it on my favorites list. I don't want to put every video I like in my favorites list.
So, here is my suggestion--do something like what Netflix does--that is, they have a thumbs up button and they have a two thumbs up button. But don't put a thumbs down button. And don't make a playlist out of the thumbs. That would make sure nobody gets his or her favorite videos downgraded, but the the producers get a better idea of what users like.
It might even work to have a thumbs up for specific scenes in the videos. That way producers can tell, for example, that lots of people like they way they shoot missionary, but maybe they don't do doggy so well.
