I think the vote button for questions is not placed well. Let me explain how I read topics so you can understand why I think that.
Every time a read a question + answers I start on the top of the page and I go down. Sometimes there is a long answer or question that might take more than my screen's height so I scroll down. If the question/answer was good I need to break my down-scrolling and go back up just to add a vote. I would like to go in just one direction...
The best place for a vote button is the bottom of the thing you have to read before voting. I the same thing as with EULAs: the (Dis)Agree button is placed below. Usually you put a button above only if you know that someone can click that without requiring to do what is below.
What do you think about that?
