When the site was first constructed, careful consideration was given to the catagories, and those chosen were deemed the most appropriate, and sub-divisions were ruled out for reasons of space and ease of management. Yes, a sub-division such as you have suggested would be an idea, but how long before the Music section is subbed into rock / pop / jazz / soul, or the Adverts into TV / film / print, and so on and so forth. I guess we have to go with the current format, and simply ignore the Questions we don't want to answer.
