That happens to be a distinction without a consequence. If the people rating are voluntary users, then the more engaged users are going to have more weight in the ratings, simply because they vote more. The ratings will therefore statistically skew towards higher engagement.

I think that's a very important distinction, because it speaks to the intentions of the creators. It's not being designed this way, it's an accident.
