The OP of a post should be able to see the +1's and -1's of the post so that they can see if it is an overall accepted or 'hated' post, and what to do to fix it, even if they don't have 1000+ reputation.
The overall of votes is shown to the user: if the score is positive then his post is good otherwise it needs improvement.
I don't think that viewing the vote count is important at all: sometimes a post get a downvote for no reason, if it is good it will probably have a positive score, so viewing that -1 is not important at all.
If you still think this is necessary to you, there is a workaround: "View Vote totals" without 1000 rep
I have it but I rarely use it.
