> I'd say a comment "this is wrong because" first, then something other than down voting. I guess its just as much a signal to people looking for an answer as it is for the person who wrote the answer. At least with a downvoted answer, its easy to see "ok, maybe not this one" and you can check the comments to see why. Not that I'm a fan of downvoting, I think a flagging system would achieve the same thing while being more helpful to all involved than an opaque downvote.
