JDate has added lots of great new features including more questions. Take the time to answer at least the original questions so that you don’t end up looking shady with tons of blank spaces. People get suspicious when you repeatedly avoid answering a question. Your basic profile (multiple choice answers) really, really ought to be answered. Then answer as many questions as you can. You don’t necessarily need to answer every quiz  (if you answer every single little question every day then you can start to look a bit overanxious (read: desperate)) but you shouldn’t make it look like you’re trying to hide something.
