Sort:  

there are 2.5 a day. It doesn't stop you from down voting more, it just means it burns voting Mana, like it did before. so there are 2.5 "free" and then it starts to cost again.

I am glad. There is something satisfying about it when justified.

very exciting to see how the downvote pool and the other changes will effect rewards, behavior, and quality eventually.

I agree as it has the potential to dynamically shift behaviors in many ways and while people focus on the downvotes, there is also going to be new possibilities for earnings.
