Cool concept! Keeping the selections to Yes / No is a good choice. Would you consider opening up a comments section after answering so people can discuss further?
Something I noticed is that the footer leaves the bottom of the page and comes up to around the middle of the page after submitting an answer. Plenty of SO solutions for that.
Thanks. I'm considering adding more question types in the future, especially multiple choice ones.
My concern with letting people comment is the moderation aspect.
What browser are you using? I couldn't repro with what I have.
