I think the downvote button and counter is legitimate and I miss it.
This site is about expressing yourself, and we shouldn't be so thin skinned.
Think of it this way, in an election, you either vote for someone you like or you vote against someone that you don't like, or you don't vote at all. That's what we had when we could see ups and downs. I could either upvote a meme, downvote a meme, or ignore it.
Now, I can only upvote it or ignore it. Yes, I can still comment, and I think that's why there are so many negative comments and flame wars now. If people could just downvote and move on they would.
I know some say that the downvote button still works, but you don't have the feedback of seeing how many there are.
Yes, I know there are some that abused the DV, but there are also those that abuse the UV.
Sorry for the multiparagraph reply, but it grinds my gears!
