Actually, there is a way you can view the votes by (gender,age-group,etc.) - click on the "Option A vs. Option B" tab right under "Who responded to your question?" Is that what you were looking for? If so, it's our fault for not making it more visible.

Thanks for the heads-up about the mturk job search - we're making tweaks so that those previews show a sample question from now on. Helps keeps the responses more random too.

Thanks for sharing it!
