I was going to ask on why enabling secret question wasn't a good idea 'cause it confused me (when it was designed to help you for retrieving your account password), and then I see this. Thanks for the input though. I was wondering few days ago if I should make one for myself but I think, I should withdraw from doing it so now :D.
Secret questions can be used if you forget your login password. As mentioned before, this will result in the account being locked, and to recover it, you must be able to prove ownership of the account by showing the PGP key or Bitcoin address associated with the account and signing it.

Yes, just keep it blank. Make sure that the secret question area isn't full of whitespace characters. (Spaces don't count, but some other whitespace/invisible characters do.)
