I just noticed this feature missing, there is only up votes.

I voted 'Bad' but now I'm not sure, it was very useful and nice to see what other people think in an easy way. I think it was an easy way to show your view on someones opinion without having to comment yourself. But on the other hand this may be a good thing too because now you have to tell why you don't agree. It's easy to downvote someones opinion without explaining why, this update encourages more interaction which is good I guess.3
