The hesitation to make a vote that is too strong leads to the lack of voting. So, in the light of my observation about hard/soft voting, I suggest making 4 buttons that explicate the distinction: (--, -, +, ++), where the central buttons correspond to the soft votes, and outside buttons to more aggressive hard votes.
