I think it's also region dependent. I notice a lot of Americans have this strong drive to be a "winner" and are very sensitive to negative criticism. The same in southern Europe (though without the ambition but they are certainly sensitive)

In the Netherlands and Germany however we are pretty blunt and can tell people if we don't like something they did and they don't really take it personal if we're not an ass about it.

So for us a downvote button would be pretty normal.
