But even if you encourage that it's still pointless, because you don't know how people have used it, or with what distribution.
This annoys me with ratings used to train recommendations too, e.g. Netflix, where I don't know how they want me to use it. What if I know it is something I would absolutely not even try watching, should I rate it? Or am I telling it I tried it, and that's a higher rating (because I might give something similar a go too) than none at all? Not to mention the old stars not being mapped into thumbs, or the later addition of double thumbs up meaning only more recently encountered favourites get that accolade.
