The problem is that it isn't clear WHY you should upvote a question. Upvoting an answer is helpful - I'm saying that I confirm that it's correct and you should believe it - but upvoting a question is just gold star time.

I upvote questions if I've wondered the same thing myself, and it's already been answered. I only use favourite to follow the discussion.
