We sometimes do it the opposite way on LW: We'll upvote something that we wouldn't normally if it has < 0 points, because we're seeking its appropriate level rather than just voting.

I don't know that anyone downvotes something because they think it's too popular. I have refrained from voting for things that I thought had enough upvotes.
