It would be cool if the site displayed the users answer after submitting. This would be really helpful on questions where there are a number of checkboxes with "choose 3" or that sort of thing. The ones where most people get it wrong because one of the options was incorrect. In those cases it would be nice to know choices were made so we can easily see what was incorrect. There have been several of these questions lately and sometimes you forget what choices you selected after hitting the submit button and finding out your answer was incorrect.
