I actually have yet to encounter a single website with this sophisticated of a rating system. It is particularly hard to find quality content on websites with a large database (i.e. YouTube). Newer videos will always have a higher 'rating' because it is 'newer'. Older videos will always have the most 'views' because it has had more time to get to that state. If you can't reach a consensus about what the most optimal rating system is, implement a nested rating system. This way, the end-user can specify to sort by 'rating' and then by 'date' and then by 'views', or however order he/she feels most optimal.
