It doesn't seem to break down how many up and how many down. Just the combined score.
Why the change? I think there is a huge difference between something that sits at 1 because nobody voted on it, or sits at 1 after 100 people upvoted it, and another 100 downvoted it.
I also fear that when downvotes are invisible, people are more prone to use them. That is just speculation though.
Edit: Ok, I think I get it. I found the video of @pembo during the code swap.
It's not finished yet in the new template. Pembo and Polsaker were 'arguing' about putting it back, not sure if they were serious. I hope Polsaker was just joking.
