As the community grows there's going to be those who abuse the downvote button; no getting around that. As long as the majority do use it correctly the upvotes should make the few abusers insignificant. So what, 2 or 3 people downvoted your submisison. Look at the other side, 51 people upvoted it. The community has spoken and those 3 downvotes mean nothing.
EDIT: I have a suggestion though, how about making upvotes and downvotes public? Like you can click on the number and it will give you a list of the usernames who up or downvoted a submission.
