I don't downvote much, but sometimes I come across a post that I feel is just retarded. I'd like to downvote it, but I hesitate when I remember that I'll be sacrificing my rep for a dumb post. I understand the negative reps is to avoid downvote abuse, but I feel it's also preventing some people from downvoting posts that deserve it.
Should we be allowed a limited number of non rep reducing downvotes per time period? For example one free downvote per day?
p.s. please don't downvote this question just to be funny :)
