You spend your reputation to downvote an answer (a question can be donwvoted freely). The positivity® is an issue too, I agree. Or maybe anti-negativity. On blender.stackexchange.com, where I'm active, we have a problem of few people caring to upvote questions. The best way yo motivate people to upvote a question is to... Downvote it. As long as a question isn't absolutely terrible, if it has negative score, people will upvote it to 0. Which generates reputation for the author of the question, because he gets -2 rep for a downvote and +10 for an upvote.
