Will we have enough candidates for all those categories?
I mean, take finance. At most 2 people can be nominated, of which you are one.
Or history. I'll soon finish my doctorate while Seven is also a history graduate. Who else can we nominate?
Or religion. A bunch of atheists who'll never vote for the Muslims and vice-versa.
If you want I can still do it, or at least do it about the categories you think we'll have enough nominees.
But my suggestion is to have only 2 "most knowledgeable" categories. Football and General knowledge.
