New players are fragile little beings...if they get bored or feel like they're filling out a survey, they'll quit out never to be seen again. I suspect you'd lose a fair amount of players if you add two more questions to character generation that are not fun.

As an example, half of the time if you see a new player (flagged newbie) struggling at the gnome and pop down to speak to them, they get spooked and just quit out. We've discussed adding 'how did you hear' information and other survey stuff to the character generation before, and as a staff always opted not to, for these reasons.
